The latest update relates to Monday morning's scene in the 12000 block of Marsham Circle in north Harris County.
Investigators initially responded to a call of a car crashing into the home. But when units arrived, they found the teen driver, identified as 18-year-old Jesus E. Zamores, dead with gunshot wounds.
Investigators said this may have been targeted violence between teenagers, with a witness telling them he was shot at before the driver of the car was killed.
Zamores and his 14-year-old cousin were in a vehicle and allegedly shot at another teen at a bus stop. But authorities said that's when Zamores was shot by his young passenger.
On Tuesday, Sheriff Gonzalez said the 14-year-old suspect, whose identity wasn't released due to age, had been booked into the juvenile detention center.
