A former cop in Virginia has been charged with second-degree murder for shooting an unarmed man in 2013, the Washington Post reports. Adam Torres, who until July 31 worked for the Fairfax County Police Department, turned himself in on Monday. The murder indictment, approved by a special grand jury that convened this summer, begins a new chapter in a case that has already stretched for nearly two years after Torres fatally shot John Geer, 46, in August 2013 as Geer stood in the doorway of his home in Springfield, Virginia.

Torres, 32, fainted and fell to the ground after he was denied bond and a judge set his murder trial for Dec. 14. Torres is facing second-degree murder charges that he wrongfully shot and killed John Geer, 46, of Springfield, Va., in a standoff stemming from a call about a domestic dispute in 2013.

Officers responding to a call from Geer’s live-in girlfriend during an argument said Geer refused to come all the way out of the house and initially “displayed” a gun in a holster, but he was convinced to put it down at his feet, according to accounts from officers and witnesses. Geer was reportedly standing with his hands resting on a storm door and conversing with officers, including one specially trained in negotiation, as Torres kept his gun trained on Geer from 17 feet away.

As the lawyers debated a trial date, Torres, who had been standing for several minutes, collapsed, first hitting a chair before landing flat on his back. As one bailiff cleared the courtroom, another checked his vital signs as Torres lay on the floor with his eyes closed.

From the Post:

Geer repeatedly asked Torres to lower his weapon. Officers said that Torres would comply but that Torres would raise it again when Geer periodically asked to scratch his nose.

[Officer David] Neil radioed to colleagues that Geer had said he wanted to take his own life, and “he might do a suicide-by-cop type of situation.”

At 3:34 p.m. as [police negotiator Rodney] Barnes continued to negotiate with Geer, Torres fired one shot at Geer without warning, surprising the other officers, they told investigators. Geer retreated inside the home, and the police report states Torres told Barnes, “I’m sorry.”

While Torres later claimed that he thought Geer was reaching for his waist and presented a threat when the shot was fired, his account was contradicted by others at the scene.

“It was not accidental,” Torres told detectives. “No, it was justified. I have no doubt about that at all. I don’t feel sorry for shooting the guy at all.”

But four officers on the scene and Geer’s father and a friend, who were also there, said Geer’s hands remained above his shoulders when he was shot.

“When the shot happened, his hands were up,” Barnes told detectives. “I’m not here to throw [Torres] under the bus or anything like that, but I didn’t see what he saw.”

Torres, who had been on administrative duty since the shooting, was fired this Julywhen Fairfax County Police Chief Edwin C. Rossler Jr. determined that Torres had violated the department’s “policies and procedures on the use of force” when he shot Geer, according to WTOP.

The department’s handling of the case brought federal scrutiny after it withheld Internal Affairs files from county prosecutors and refused to release Torres’ name and other information about the shooting to the public until compelled by a court order in January 2015. In February, with the Department of Justice monitoring the investigation, U.S. Sen. Chuck Grassley sent a letter to Rossler to demand an explanation for the department’s lack of cooperation with the “unnecessarily” delayed probe. The county agreed in April to pay a $2.95 million settlement to Geer’s two teenaged daughters.

The Washington Post report on Torres’ arrest highlights the rarity of such charges for American police officers who use their weapons in the line of duty, even when they fire on unarmed people, citing a study the paper conducted with Bowling Green University that found only 54 officers have been charged among thousands of officer-involved shootings.

If convicted on the second-degree murder charge, Torres faces up to 40 years in prison.
