LAREDO, Texas — A U.S. Border Patrol agent has been charged with murder after police say he stabbed his wife to death and left their children home alone.

Abel Garza, 30, was arrested after officers spotted him driving away with his fatally injured wife in the back seat, according to the Laredo Police Department.

Authorities said Garza had gone door-to-door asking neighbors for help before officers arrived at the scene. His wife later died from multiple stab wounds.

Police subsequently discovered the couple’s children unattended, leading to additional charges of child endangerment against Garza.

Garza remains held in jail on a $1 million bond.
