A late-night stabbing on Sheffield Avenue left a 21-year-old woman in the hospital early Sunday, and state police are now trying to sort out what happened in the overnight chaos in Aliquippa.

Aliquippa officers were first called to the 400 block of Franklin Avenue around 1 a.m. for the incident. They requested backup from the Pennsylvania State Police, which has since taken over the investigation. The woman, who was stabbed once in the arm, was taken to a Pittsburgh hospital, where officials said she is expected to make a full recovery. No arrests have been announced, and investigators have not released a motive.

What state police released

In a public information release, troopers said the 21-year-old victim told investigators she was stabbed in the arm on Sheffield Avenue and then taken to a Pittsburgh hospital, where she is expected to make a full recovery, according to TribLIVE.

Troopers described the suspect as a Black man about 30 years old and urged anyone with information to call investigators at 724-773-7400, WPXI reported. Police have not said whether the victim knew her attacker.

A string of recent incidents

The stabbing adds to a tense run of violent incidents in Aliquippa this year. In February, a man was charged after a separate stabbing at the Towne Tower Apartments, and in April, troopers issued a public appeal to identify a suspect in an attempted theft that left a woman injured near the 400 block of Franklin Avenue, according to Beaver County Radio. Local officials have increasingly leaned on state police to handle major investigations in recent months.

How to report tips

Anyone with information about Sunday’s stabbing is asked to contact the Pennsylvania State Police Beaver barracks at 724-773-7400. Tips may also be submitted anonymously through PSP tip lines, and investigators are urging neighbors who saw anything or have relevant video to come forward.
