A mother found her two children dead along with their father in an apparent murder-suicide, police said.
The woman found her 5-year-old girl and a 9-year-old boy shot to death along with their dad in a North Richland Hills home on Saturday just after 7 a.m., police said. She immediately called authorities.
Police believe the father, who has not been identified, shot the children with a shotgun before shooting himself.
Police said they never had any calls to the home before.
Neighbors told CBS News that they had just seen the family out putting up Christmas decorations just a few days prior.
"You can drive by and they can have a perfect house, but you don't know what's going on inside the house. It's so sad," neighbor Rosa Nichols told the station.
Nichols, who lives a couple of houses away, said the family moved in just a few months ago.
"You never know. You just have to be kind to people when you have a chance because you don't know what they are going home to," Nichols added.
Police have not yet released the names of the victims.
