A 10-year-old boy fatally shot his father Friday, striking him several times as he sat in the front seat of a SUV to pick up the boy from his mother’s home for a weekend visit.

The incident happened about 3:45 p.m. on a cul-de-sac (死胡同)in the 1700 block of Cedar Cove Court, said Sgt. B. E. Williams of the Harris County Sheriff’s Department.

An investigation found that Rick James Lohstroh, 41, was shot by his son, who was sitting in the back seat of the man’s Toyota 4-Runner, said Sgt. B. E. Williams of the Harris County Sheriff’s Department. The shooting took place outside the home of Lohstroh’s ex-wife, where the boy lives with his mother and a 7-year-old brother.

“We’re not certain of anything until we finish our investigation,” Williams said. “The information we have at this time is that the 10-year-old did fire the weapon.”

The mother and the 7-year-old were inside the house when the shooting occurred, said Williams.

Williams said the gun belonged to the boy’s mother. After firing shots through the back seat, the boy exited(退出) the back of the vehicle and continued to fire at the car.

The man died on the way to Memorial Herman Hospital. Lohstroh was a doctor at the University of Texas Medical Branch. The man and woman shared custody(监护)of the children. Williams said the mother and the boy were still in the home talking to investigators Friday night.

Neighbors described the family as being quiet and keeping to themselves.

Justin Gray, 17, was walking in the neighborhood when he heard gunshots. “We’ve had a suicide(自杀)in this neighborhood once, but never anything like this,” Gray said.
