LANCASTER, Ohio (WCMH) — Three teenagers and a 21-year-old were arrested Wednesday in connection with the fatal shooting of 16-year-old Haylen Tabor.

Lancaster police say they were called to the 1100 block of Locust Street about 3:45 p.m. Tuesday on report of a robbery and shooting, where they found Tabor suffering from a gunshot wound inside a residence.

Tabor was flown by helicopter to Nationwide Children’s Hospital, where he died on Wednesday afternoon.

Investigation revealed the gunshot wound occurred as a result of a robbery involving four masked suspects. The suspects were identified as Brandon McNally, age 21, and three 16-year-old males. All four were arrested without incident and are in police custody. An unknown amount of cash and marijuana was stolen during the robbery, police say.

McNally and the three juveniles are facing charges of aggravated robbery and battery, with charges related to Tabor’s death pending.

Lancaster City Schools issued a statement about Tabor, saying it has assembled a crisis counseling team for anyone who might need those services.
