HOUSTON – Two kids  were shot while sitting in their car in south Houston overnight.

According to the Houston Police Department, the incident occurred shortly before midnight near Scott Street and 610 Loop.

The victims were sitting at a red light when a vehicle pulled up near them, and someone in the car started shooting.

“The possible suspect description is going to be a silver or gray Chrysler 200,” says Captain Meagan Howard with the Houston Police Department.

Police said the 15-year-old boy, who was driving, was shot in the arm and his sister, age 12,  was shot in the hip.

The victims were taken to Houston Fire Station 46 for assistance. When they arrived, the father of one of the victims was with them.

The boy was taken to Ben Taub Hospital and the girl was taken to Texas Children’s Hospital. Both are expected to survive.

Investigators say they had a friend riding in the front seat who wasn’t hurt.

“At this time we don’t have a motive. We’re not sure what the relationship is,” Howard said.
