FBI Norfolk is advancing the investigation of the shooting with a 3D scan of Building 2 that helps "paint a clearer picture" of the gun battle and evidence left behind.
Special Agent in Charge Martin Culbreth said a team from Quantico is helping the Bureau reconstruct the scene with 3D technology. He said investigators will continue to review the crime scene through Friday and potentially into early next week.
“In a scene that is as complex as this and a building that is this old and has so many offices and cubicles and filing cabinets, we want to make sure we're as thorough as we can be," Culbreth said.
The FBI is assisting Virginia Beach investigators with evidence recovery and other parts of the investigation.
“We have teams that are down here that are experts in reconstructing what happened and providing a timeline, finding where all the different evidence is located and how it got there," Culbreth said. "It’s what would be expected for the dignity of the victims involved”
Culbreth said the shooting is a "gutwrenching, terrible tragedy" for Virginia Beach and Virginia Beach Police investigators, who are working the crime scene "in their own backyard."
Virginia Beach Mayor Bobby Dyer allotted time for each Virginia Beach City Council member to speak about the tragedy before Tuesday afternoon's city council workshop. Dyer and others pledged to act to honor the victims and their families.
"The foundation of our soul has been rocked but we will respond," Dyer said. "We will be there for them now and we will be there for them forever, through this adversity we will become stronger."

A top gun rights advocate in Virginia says Gov. Ralph Northam's plan for a special legislative session on gun control is "political theater."
Philip Van Cleave is president of the Virginia Citizens Defense League. He says he "can't think of a single gun control thing that would have prevented what happened at Virginia Beach," and accuses the governor of "trying to deflect from his recent foibles."
The gun lobbyist said it's "pure baloney" that silencers mask the sound of gunshots.
His solution to Friday's killings of 12 people would be loosening restrictions on Virginia Beach city employees from being able to carry concealed handguns at work. He says "there's really nothing other than allowing people to protect themselves until the police get there that would have worked."
6:30 a.m., June 4
City officials return to work Tuesday following the deadly shooting.

The FBI is assisting the City of Virginia Beach in "evidence recovery" at Building 2 on the city's government campus. A FBI spokeswoman said agents from multiple east coast FBI offices will investigate the scene through Friday.
Virginia Beach Mayor Bobby Dyer said the city is making accommodations so employees will not have to return to Building 2 "for at least a long while." He said he doesn't want his employees to relive trauma as many of them return to work on Tuesday.
"It was first a shock, but the reality is setting in," Dyer said. "We're going to deal with the people first - the emotion and the trauma. We're going to come back stronger, you have my word on that."

Officials in Virginia Beach have released the brief resignation letter that was submitted by the man who police say fatally shot 12 people at the municipal building where he worked.
It gives no hint about what he planned to do or why.
DeWayne Craddock's partially redacted resignation letter was released Monday. He said it "has been a pleasure to serve the city, but due to personal reasons I must relieve my position."
The 40-year-old wrote that he wanted to "officially put in my (2) weeks' notice" and vacate his position of "Engineer III with the City of Virginia Beach."
An unidentified person responded stating that he or she hoped that Craddock is able to resolve his personal issues and that Craddock's last day would be Friday June 14.
Craddock responded, writing "Thank you. Yes, that is correct."
The shooting began sometime later.
Authorities say 12 people were killed and several others wounded when DeWayne Craddock opened fire inside the municipal building Friday afternoon. Craddock was killed during a gunbattle with police.
Officials have given no indication why 40-year-old Craddock notified a superior of his intention to leave his job. City Manager Dave Hansen says he was an employee "in good standing."

The Washington Post reports the note was taped Saturday to the front door of the two-story house on the wooded road where DeWayne Craddock lived about an hour from the city.
It says: "The family of DeWayne Craddock wishes to send our heart felt condolences to the victims. We are grieving the loss of our loved one." It says Craddock's family wants to focus on the victims of the shootings and offers thoughts and prayers for the relatives of the dead and wounded.

Investigators are still combing through evidence and interviewing witnesses to determine how Friday's mass shooting at the Virginia Beach Municipal Center happened... and why.
FBI agents continue to actively work just feet from a memorial of 12 American flags and bouquets of flowers. It is a stark reminder of the tragedy that is still hard to grasp.
"Now that we've had 24 hours, some of the numbness is wearing off and it's starting to sink in about these people who have died," said Drew Lankford with Virginia Beach Public Works.
Lankford knew most of the victims who worked in his department. A woman he was closest to just had a baby.
"It couldn't have been easy, saying goodbye to the baby yesterday morning," Lankford said. "She was just going to work. That's what really eats at me about this guy."
At a press conference on Saturday, police confirmed a long-time city worker was the gunman. Police said he went floor-to-floor in Building 2, shooting indiscriminately until police officers shot him dead in what Chief Jim Cervera called a long gun battle that lasted several minutes.
An ATF agent said the shooter used two .45 caliber pistols in his rampage.
"Both pistols were purchased by the shooter and all indications are they were purchased legally," said ATF regional special agent Ashan Benedict.
Authorities said two additional guns were found at the shooter's home, where he lived by himself.
"At this time, we're also working with our law enforcement partners to look at the ballistics from the weapons discharge, and also the ballistic knifing to see if they correspond with any other shootings," said Benedict.
"It's a time-consuming, meticulous process," Chief Cervera added. "It is not what you see on TV. It is not what you see in the movies."
Police are still investigating a motive. They're tight-lipped about any additional evidence found in the suspect's house and if they have reason to believe the attack was planned.
"It's not just arrogance, it's evil," Lankford said of the gunman. "Uncaring. I don't want to hear any excuses."

Four were engineers who worked to maintain streets and protect wetlands. Three were right-of-way agents who reviewed property lines. The others included an account clerk, a technician, an administrative assistant, and a special projects coordinator. In all, they had served the city of Virginia Beach for more than 150 years.
These 11 city employees and one contractor were wiped out Friday when a fellow city worker opened fire inside a municipal building. A day after the shooting, city officials sought to honor them by sharing their job titles and years of service in a somber slideshow.
"They leave a void that we will never be able to fill," said City Manager Dave Hansen, who had worked for years with many of the dead.
Police Chief James Cervera identified the assailant as DeWayne Craddock, who had been employed for 15 years as an engineer with the city's utilities department. He declined to comment on a motive for the rampage, which ended with Craddock's death in a gun battle with officers. City officials uttered his name just once and said they would not mention it again.
Joseph Scott, an engineering technician with the utilities department, said he had worked with Craddock and had a brief interaction with him Friday, passing him in the men's restroom about five minutes before the shooting.
"He was in there brushing his teeth, which he always did after he ate," Scott said. "I said 'Hey, how you doing? What are you doing this weekend?' It was just a brief conversation."
Scott said he left for the day right after and learned of the shooting when a co-worker and then his son called him asking if he was OK.
"I couldn't believe that it happened," he said.
One of the dead employees had worked for the city for 41 years. Six worked in the same department as Craddock, though authorities have declined to say if anyone was specifically targeted or if the suspect had issued threats before. The victims were found throughout the building, on three floors, police said.
The municipal building was open to the public, but security passes were required to enter inner offices, conference rooms and other work areas. As a current employee, Craddock would have had the pass to enter the inner offices, Hansen said.
In response to a reporter's question, Cervera said the gunman had not been fired.
One of the dead, Christopher Kelly Rapp of Powhatan, enjoyed Scottish music and joined a pipe band last fall. He played with the group in October during a Celtic festival in Virginia and marched with bandmates on St. Patrick's Day.
"Chris was reserved but very friendly, quietly engaging members one-on-one after our weekly practices," the band, Tidewater Pipes & Drums, said in a statement.
Another victim, Mary Louise Gayle of Virginia Beach, was described as a "super sweet lady" who always had a big smile. "She would always be out there in the yard, working on something and talking to my daughters," John Cushman, Gayle's next-door neighbor, told The New York Times.
The other employees who were killed were identified as Tara Welch Gallagher, Alexander Mikhail Gusev, Katherine A. Nixon, Ryan Keith Cox, Joshua O. Hardy and Michelle "Missy" Langer, all of Virginia Beach; Laquita C. Brown and Robert "Bobby" Williams, both of Chesapeake; and Richard H. Nettleton of Norfolk. The 12th victim, Herbert "Bert" Snelling of Virginia Beach, was a contractor who was in the building to seek a permit.
The police and fire departments were to assign members of their honor guards to help each victim's family.
4:30 p.m., June 1
An official with the federal Bureau of Alcohol Tobacco Firearms and Explosives says investigators have identified two .45 caliber pistols used in the shooting at a Virginia Beach municipal building that killed 12.
Speaking at a news conference Saturday afternoon, ATF regional special agent Ashan Benedict says all indications are that the guns were bought legally. He says one gun was bought in 2016 and the other was bought last year.
Benedict says two other weapons were found at the gunman's home.
Meanwhile, President Donald Trump ordered U.S. flags to be flown at half-staff in memory of the victims.
Trump said in a statement released by the White House on Saturday that he was ordering the action as a "mark of solemn respect for the victims of the terrible act of violence" on Friday.
Three victims who survived the shooting remain hospitalized with serious injuries at Sentara Virginia Beach General Hospital.
Dr. Martin O'Grady told a news conference Saturday that one patient had just gotten out of surgery and another patient faced repeated operations for wounds inflicted when a gunman opened fire at a municipal building in Virginia Beach.
O'Grady is head of the hospital trauma unit. He said two of the patients being treated at the hospital had sustained "significant" injuries but were expected to survive. He described a third patient's injuries as "devastating." He would not elaborate due to health care privacy laws.
Authorities said earlier that a fourth patient was receiving treatment at a hospital in Norfolk.

"And that didn't happen for them. And we must remember they all had families they all had loved ones, they were parents, they were daughters, sisters, brothers — and now there's a void in their families."
The Norfolk FBI is asking the public for information about the shooting.

ABC News said two law enforcement officials who'd been briefed on the investigation said DeWayne Craddock recently was fired from his position as a city employee.
----------
Virginia Beach Police say 12 people are dead following a shooting at the Virginia Beach Municipal Center. The suspected shooter is also dead following a shootout with police.
Virginia Beach Police Chief Jim Cervera said the suspect was a current, longtime employee of Virginia Beach Public Utilities who opened fire and shot "indiscriminately" at workers inside an operations building in the Virginia Beach Municipal Center on Friday afternoon.
Chief Cervera initially said there were 11 victims killed total, in addition to the suspected gunman who was killed by police in a shootout. In a later update, Cervera confirmed a 12th victim had died while being taken to the hospital.
The police chief did not identify the suspect, but two law enforcement sources confirmed to ABC News that DeWayne Craddock, 40, is the alleged suspect in the shooting.
Cervera said the gunman used .45-caliber handgun with a suppressor.
Cervera added that a long gun battle erupted between the shooter and four police officers.
According to Dale Gauding, a spokesman for Sentara Healthcare, three patients are in Sentara Virginia Beach General Hospital, two being in critical condition and one in fair condition.
Gauding said Sentara Virginia Beach General first received five patients, but two have died.
One patient at Sentara Norfolk General Hospital in critical condition. That patient first went to Sentara Princess Anne Hospital near the city complex, but was later picked up by Sentara Nightingale Regional Air Ambulance and flown to Sentara Norfolk General Hospital, the regional Level I trauma center.
One other patient arrived at Sentara Princess Anne Hospital on their own and has since been released.
At a news conference, Virginia Beach Mayor Bobby Dyer described it as "the most devastating day in the history of Virginia Beach."
Municipal Center, Building 2 holds several city governmental operations, including public works, public utilities, and planning departments. It is adjacent to City Hall.
The victims were found across three floors of the building, with one victim shot in a car outside the building.
In a statement, Governor Ralph Northam called it "a horrific day for the Commonwealth of Virginia. We are devastated by the tragic shooting in Virginia Beach. I am in Virginia Beach with law enforcement authorities and Mayor Dyer, where I am monitoring the situation and offer the state’s full support."
Northam also said, “My deepest condolences and prayers go to the families of those who left home this morning, and will not return tonight, as well as those who have been injured in this tragedy.
"This is unspeakable, senseless violence. I commend local and state law enforcement, first responders, medical teams, and all others who acted swiftly to respond to this situation. My thoughts continue to be with the victims and their families."
Families and loved ones of employees at the Virginia Beach Municipal Center who are not hearing anything can go to Princess Anne Middle School at 2323 Holland Road.
Megan Banton, an administrative assistant who works in the building where the shooting happened, said she heard gunshots, called 911 and barricaded a door.
"We tried to do everything we could to keep everybody safe," she said. "We were all just terrified. It felt like it wasn't real, like we were in a dream. You are just terrified because all you can hear is the gunshots."
She said she texted her mom, telling her that there was an active shooter in the building and she and others were waiting for police. Banton works in an office of about 20 people that is part of the public works department.
"Thank God my baby is OK," Banton's mother, Dana Showers, said.
A spokesperson for the FBI confirms the bureau is assisting Virginia Beach Police.
