Police are searching for suspects who fired into a Dallas apartment early Tuesday morning, leaving a 10-year-old and 13-year-old hospitalized, police said.

Officers responded about 2:15 a.m. to an apartment complex in the 9400 block of Royal Lane near Abrams. They found a man and two children inside the location, police said.

The 13-year-old boy was shot in the back of the head and the 10-year-old was grazed by a bullet to her back. The 37-year-old man, the childrens' father, was not injured.

The man's mother, Stephanie Davis, said people were running through the complex at the time and that's where the bullets came from. She said her son is not to blame.

"Who ever thought this would happen? My son don’t do drugs. He don’t sell drugs. None of that. He’s a family man. At night he takes his kids to the park and after eating or whatever. He’s still a family man," Davis said.

Police said the victims were in stable condition at Dallas Children's Medical Center after the shooting. Davis said the 13-year-old was to have surgery Tuesday afternoon to remove a bullet from his neck.

Davis, who lives nearby, said she watches the children during the day when their father is at work during the summer time. When school is in session, Davis said they live with their mother in Forney.

Some neighbors said there has been trouble at the complex before but Davis said nothing like this.

"I’ve been here eight years and we aint never had anything like this going on here," she said.

The grandmother had a message for the shooter.

"Just think about it before you shoot somebody else’s child. Suppose that was your child," she said.

Officers searched for suspects at the apartment complex but no arrests were reported Tuesday.
