Police in Texas have arrested a police officer for the death of his brother and his wife, who police say were shot during an argument in their home on Friday.
The officers, who were responding to a call about a man in a nearby yard, said they saw the suspect in a yard and that he was wielding a weapon.
The two men were inside the home with a woman and two children, and the officer said he heard the gunshots, the department said.
The officers returned fire, and they say the suspect fled the scene.
A woman, whose husband died at the scene, was shot in the chest and taken to the hospital.
She was listed in critical condition, police said.
The suspect was arrested and charged with three counts of aggravated assault on a peace officer and four counts of malicious wounding.
He is being held on $500,000 bond.
