Prosecutors accuse him of recklessly firing the shot that killed Akai Gurley

New York CNN  — 

A jury will enter its third day of deliberations Thursday in the trial of a New York police officer who shot and killed a man in a housing project stairwell.

Officer Peter Liang faces five counts in the 2014 death of Akai Gurley, 28: manslaughter, assault, reckless endangerment, criminally negligent homicide and official misconduct.

The case went to the jury Tuesday afternoon. Jurors were sent home after about an hour of deliberations. Court is expected to resume Wednesday morning.

During closing arguments, the officer’s lawyer called the fatal shooting tragic, but not a crime, stressing that Liang followed procedures. Police determined that Gurley was “a total innocent.”

“What happened here is a tragedy,” defense attorney Rae Koshetz said. “It’s a terrible tragedy, but it’s not a crime.”

Prosecutor Joe Alexis argued that Liang showed poor judgment, again and again, and that the shooting wasn’t an accident beyond the officer’s control. He asked jurors to hold Liang accountable.

The trial has garnered attention beyond New York because of the national controversy over allegations that police are too quick to use lethal force, sometimes against unarmed people. Outrage over police shootings or excessive use of force has spurred protest movements in major cities such as Chicago, Baltimore and New York.

In the most well-known cases – the fatal shootings of Michael Brown in Ferguson, Missouri, and Walter Scott in North Charleston, South Carolina, and the death of Freddie Gray while in police custody in Baltimore – the victims were unarmed black men.

‘An accidental discharge’

Gurley was shot in the chest in Brooklyn and died at a hospital in November 2014.

The next day, police Commissioner William Bratton told reporters the 28-year-old was “a total innocent” who fell victim to “a very unfortunate tragedy … involving an accidental discharge.”

On Tuesday, the defense told jurors that Liang handled his firearm as trained, and that the video of the crime scene shows that having his weapon drawn in the darkness of the stairwell was the correct course of action.

Liang gave tearful testimony on the stand Monday, just before both sides rested in the case. He lost his composure when asked to recount what happened in the stairwell on that night.

“I was panicking. I was in shock, in disbelief that someone was actually hit,” he said.

The prosecutor has accused the rookie officer of recklessly shooting into a dark stairwell “for no reason.”

“Then, instead of doing all that he could to help Akai Gurley, he wasted precious time arguing with his partner about calling for help,” Assistant District Attorney Marc Fliedner told jurors. “In fact, instead of calling for help, he just stood there and whined and moaned about how he would get fired.”

As they made their case Monday, prosecutors played a 911 recording of neighbor Melissa Lopez shouting CPR guidelines to Gurley’s girlfriend as he lay bleeding on the ground. In the recording, Lopez tells the dispatcher she sees numerous police officers, but no paramedics, at the scene.

“He’s shaken and terrified and totally, and I mean totally, unaware that a bullet has struck anything. At that point, sure, he’s upset about losing his job, (but) he has no idea that anything else had happened,” defense attorney Rae Koshetz said.

When Liang and his partner went back into the stairwell to investigate, they discovered Gurley and his girlfriend on a stair landing below, Koshetz said.

“The evidence in this case will show that this was a million to one possibility. The bullet had traveled downward, hit the cinderblock wall on the side of the stairs and then ricocheted and hit Mr. Gurley a floor below and completely out of sight. And it hits him on his left side,” she said. “It is a fatal wound and you will hear that no amount of CPR would have saved his life.”

Gurley’s family: Not buying it

Gurley’s family was less than sympathetic at a Monday afternoon news conference.

“Peter Liang says that it was an accidental death. Peter Liang, my son was no accident,” said Sylvia Palmer, the victim’s mother. “You murdered my son. I need justice for my son. I need a conviction of Peter Liang.”

Stepfather Kenneth Palmer said the trial has taken its toll on the family.

“If you fire a gun and you know you’re guilty, say ‘I’m guilty’ and that’s it,” he said. “Don’t put any family through what we’re going through.”

The 2014 shooting death came amid strained relations between police and the community, just a few months after the death of Eric Garner in police custody in Staten Island. The chokehold death of Garner, an unarmed 43-year-old man, sparked street protests, a review of police procedures and calls for a federal civil rights investigation. A grand jury declined to prosecute the officer.

Liang was indicted last February. If he’s convicted of second-degree manslaughter, he could face up to 15 years in prison. At the time of his indictment, the head of the police union said he deserved due process.
