ALBUQUERQUE, N.M. — A 32-year-old man is facing murder charges in the road-rage killing of a 4-year-old Albuquerque girl, who was shot in the backseat of her father’s truck — a death that horrified the public.

Police said Tony Torrez was arrested Wednesday and admitted to the shooting in the death of Lilly Garcia.

The announcement came a few hours after police said a person of interest had been taken into custody.

Lilly was riding in the backseat with her 7-year-old brother after they were picked up from school Tuesday when someone in a Toyota opened fire on the family as they traveled down the main east-west freeway in Albuquerque.

The father told authorities that he was trying to exit I-40 when a car forced him out of his lane, according to a police statement.

“The two drivers exchanged words when Torrez pulled out a gun and shot at the red truck driven by Lilly’s father,” the statement continued. “Lilly was hit at least once in the head.”

The father quickly pulled over and tried to administer first aid to his daughter as a bystander called 911.

In the roughly minute-long call released by police, a man is heard alerting an operator to a truck stopped on the median on Interstate 40 on Albuquerque’s west side with “an adult holding an unresponsive child.”
