Witness statements to police say an argument over child custody may have prompted the double shooting that left Kierra Harris and Lavon Sizemore dead.

What began inside of a home on Kelly Street, according to court paperwork, when 29-year-old Sizemore and 26-year-old Harris arrived later spilled into the street.

One of two witnesses told investigators another man and woman arrived outside a short time later and then they heard gunfire.

The witness told authorities the couple that arrived left and Harris was seen staggering and then fell to the ground.

Sizemore was found dead inside a car.

Another eyewitness told police he was watching from the second-story bedroom of a nearby home and saw a group of men and women in a verbal and physical altercation near a black car.

That witness says they saw a black man that was standing near that car fire two shots, and then the man ran down Kelly Street.

A KDKA news tip turned over to police helped lead investigators to Barnett.

Barnett, of Mohler Street in Pittsburgh, fled to Philadelphia.
