HOUSTON — A judge has denied bond for an 18-year-old Houston man accused of fatally shooting an 8-year-old boy who was in a car with his younger sister when they were caught in a drive-by shooting that police believe was gang related.

Devonte Lockett was arrested last week and charged with murder for the slaying of Tristian Hutchins. He died March 28, four weeks after he was shot. His 5-year-old sister was wounded in the leg.

Witnesses told police Lockett was firing from the passenger seat of a vehicle. Houston officials had pleaded for help finding the gunman and police say others are being sought.

Lockett’s bond request was denied Saturday. He’s scheduled for another court appearance Monday.

Records show he has a previous arrest for carrying a handgun in a vehicle.
