Nouman Raja, 41, was charged in 2016 after a grand jury found he had used unjustified force when he shot and killed 31-year-old Corey Jones while wearing plainclothes on a highway exit ramp in West Palm Beach. Prosecutors said Raja, who was fired from the Palm Beach Gardens Police Department after the shooting, did not identify himself as a police officer.

Raja looked distraught as the jury read the verdict after five hours of deliberations. He was then was placed in handcuffs and escorted out of the courtroom. He faces a maximum sentence of life in prison when he is sentenced on April 26.

Relatives of Jones left the West Palm Beach courtroom in tears, hugging each other and raising their hands in praise.

“It was truth that convicted him. It was truth that brought him to justice. It was the truth that sent him to jail,” the victim’s father, Clinton Jones, told reporters outside. “It was truth that gave us justice for Corey.”

Jones’ brother, Clinton Jones Jr., said the family knew he was innocent from day one. “From his character alone, it’s just impossible for him to do that,” he said during a news conference.

Raja’s lawyer, Richard Lubin, argued on Wednesday that the police officer feared for his life when Jones pulled out a gun during the roadside encounter, according to WPEC CBS12 News.

Lubin did not immediately respond to a request for comment on Thursday.

Raja was driving an unmarked van when he approached Jones early on Oct. 18, 2015, and fired six shots at the victim within 13 seconds, according to prosecutors.

Jones, who was a drummer, had pulled out a .380-caliber handgun that he had legally purchased three days earlier. He was hit three times and died of a gunshot wound to his chest.

Audio from the incident was captured on a recording of a roadside assistance call that Jones had placed before Raja arrived. According to prosecutors, the recording showed that Raja did not identify himself as a police officer.

Protesters held a peaceful rally in Palm Beach Gardens four days after Jones was killed, and dozens of mourners attended his funeral more than a week later.

The Rev. Al Sharpton was among those who spoke at the memorial service, where pallbearers wore hats and jerseys of the National Football League’s Oakland Raiders, Jones’ favorite team.

Benjamin Crump, a lawyer for Jones’ family, said at the news conference that the musician was passionate about helping people and playing his music.

“Without that tape recorder, he (Raja) would have lied and his proclamation that he was standing his ground would have reigned supreme,” Crump said.
