BAKER — Police booked a 17-year-old suspect early Friday in the shooting death of an acquaintance, Police Chief Mike Knaps said.

Detectives questioned Derrick Shynell Lucas Jr., of Baker, Thursday night about the fatal shooting of Joshua Troy Weathersby, 19, whose body was found Thursday morning near the railroad tracks along La. 19, the chief said.

Lucas, of 2602 Boxwood Drive, was booked with second-degree murder and illegal use of a weapon.

Knaps said interviews with the victim’s family revealed that Lucas, a known acquaintance of Weathersby, was the last person known to have been seen with the victim on Wednesday.

Detectives questioned Lucas Thursday night, and the suspect eventually admitted that he shot Weathersby after the two got into an argument.

Lucas told police that after the argument turned into a physical altercation, the two struggled over a .380-caliber pistol that Lucas claimed Weathersby pulled from a backpack, according to a detective’s statement used to obtain an arrest warrant.

Lucas said the weapon discharged but the shooting was in self-defense. He told police he fled after the shooting, leaving the weapon and the backpack on the ground near Weathersby, Detective Avery Johnson said in his statement.

A Bakerfield subdivision resident found Weathersby’s body while on a morning walk.
