Baton Rouge Police Detectives are looking for the cousin of the 16-year-old boy who was gunned down Monday morning inside his Old South Baton Rouge home.

They have issued an arrest warrant for Devon Bowie, 19, of 1108 St. Joseph St., for second degree murder and illegal use of a weapon. Bowie is described as about 5 foot 10 inches tall and weighing 135 to 140 pounds.

Bowie is accused of shooting his cousin, Patrick Williams, after a confrontation from an ongoing dispute, said Cpl. Don Coppola Jr., a Baton Rouge police spokesman.

Williams died on the scene as Bowie fled the area in a white, four-door 1998 Oldsmobile Aurora, bearing LA Temporary Tag No. 15352005, Coppola said. Police said the teen was shot several times.

Williams had been living with family for the past two months at the 1108 St. Joseph St. residence listed as Bowie’s address, Coppola Jr. said.

Peter Dudley, an attorney who represented Williams in a robbery case last year in Juvenile Court, said on Monday that he was saddened by news of the shooting.

“He had gotten in a little spot of trouble, but he was a very nice and well-mannered kid when he was with me,” Dudley said. “He was respectful. He used manners.”

Williams had been on probation for simple robbery at the time of his death and was one of three juveniles found to have committed a robbery at LSU in April, Assistant District Attorney Curtis Nelson Jr. said.

The victim of the robbery, an LSU student, told authorities that he had been robbed at gunpoint while two of the juveniles rifled through his pockets and stole his wallet and cellphone.

LSU police found the teens walking down Highland Road a short time later and took them into custody.

The robbery did not appear to be gang related, Nelson said, but rather a decision by three youths to “go rob someone for quick money.”

Williams had been scheduled to appear in court later this month for a routine hearing on his probation, according to his attorney.

Williams’ death marked the second homicide and the first fatal shooting of the year in East Baton Rouge Parish.

The first slaying occurred New Year’s Day when Michael Taylor Sr., 53, was mortally wounded by someone wielding a tire iron in what police described as a “family brawl” in the 1200 block of Convention Street. Taylor succumbed to his injuries Jan. 7, and detectives are still investigating the case.
