FLORIDA, USA (AP) — A fired Florida police officer was found guilty of manslaughter and attempted murder yesterday for fatally shooting a stranded black motorist, becoming the first officer in the state to be convicted of an on-duty shooting in 30 years.

Nouman Raja, 41, faces a mandatory minimum of 25 years at sentencing April 26, and could spend his life in prison for the death of Corey Jones, 31.

The four-man, two-woman jury deliberated for four hours. Raja didn’t react as the verdict was read. About 25 relatives and supporters of Jones looked on, some weeping. One said “the sweetest sound was the click of those handcuffs” after Raja was led away.

They held a prayer circle outside the courtroom, shouting praise for the verdict as many sobbed. A housing inspector and part-time drummer, Jones came from a family of Christian ministers and was scheduled to perform at church the morning he died.

“Corey has been here; his soul is not here but he is definitely here in our hearts,” said C J Jones, the victim’s brother and a former Cleveland Brown football player. “He walked us through this.”

Raja’s attorneys left without comment. His wife said an obscenity when asked for comment.

Prosecutors said Raja, one of few police officers nationwide convicted of an on-duty shooting, escalated what should have been a routine interaction.

Prosecutors charged Raja with manslaughter, saying his actions created the confrontation and showed “culpable negligence”. They charged him with attempted first-degree murder, saying that although they couldn’t prove beyond a reasonable doubt which of the six shots killed Jones, the second volley was a conscious effort to kill him as he fled.

Raja, of Asian descent, was working on an auto burglary investigation team when he spotted Jones’ SUV at 3:15 am on October 18, 2015. Jones was returning home from a nightclub performance when his vehicle stalled. He had a concealed-weapons permit and carried a .38-caliber handgun, purchased days earlier to protect his $10,000 drum set, which was in the SUV.

Wearing plain clothes, Raja drove an unmarked van the wrong way up an off ramp and stopped a few feet from the broken-down vehicle.

The prosecutor said Raja never identified himself as an officer and acted so aggressively that Jones must have thought he was about to be carjacked or killed. Raja said he first thought the SUV was empty, but then saw Jones inside. Raja’s supervisor testified the officer had been told to don a police vest if he approached a civilian. He didn’t. Prosecutors also questioned why Raja didn’t pull his badge from his pocket.

What police didn’t know at first was that Jones had been talking to a tow-truck dispatcher on a recorded line. That recording shows Jones saying “Huh?” as his door opens. Raja yells, “You good?” Jones says he is. Raja replies twice, “Really?” with Jones replying “Yeah.”

Suddenly, Raja shouts at Jones to raise his hands, using an expletive. Jones replies, “Hold on!” and Raja repeats his demand.

Prosecutors believe Jones pulled his gun and tried to get away. Raja fired three shots; Jones ran down an embankment. Prosecutors said he threw his gun, found 125 feet (38 metres) from his body, but Raja fired three more times, 10 seconds after the first volley. Jones was killed by a bullet through his heart.

A medical examiner testified Jones would have dropped feet from where the fatal shot struck him. He also was shot once in each arm.

C J Jones said his brother “was a good person” who wouldn’t have confronted Raja.

“If that dude would have said he was a police officer right off the bat, this would have never happened,” he said.
