NORTH VERSAILLES, — Authorities say a woman being sought in a shooting in a Western Pennsylvania Walmart that critically wounded another woman is in custody.

Allegheny County police say 22-year-old Rojanai Alston of Penn Hills surrendered to county police Saturday evening and was taken to county jail to await arraignment.

Police said earlier Alston faces attempted homicide and aggravated assault charges in the Friday shooting in the electronics section of the store in North Versailles.

Detectives allege she got into a fight with two other women and opened fire, hitting a 25-year-old woman multiple times. The reason for the altercation and the motive for the shooting weren't immediately known.

Court documents don't list a defense attorney. A message was left Saturday at a number listed for her address.
