Police are theorizing that a quadruple shooting that left 3 people, including a student dead in East Kingston on Monday, was gang-related.

Dead are 15-year-old Marquise Morgan of Holy Trinity High school, 20-year-old Troy Dennis and 23-year-old Sabena Clarke.

A 15-year-old student from another corporate area school remains hospitalized. His wounds are not considered serious.

Reports are that at about 3 PM, the four were along Wild Street when they were attacked by gunmen in a black motor car.

They were taken to hospital where Morgan, Dennis and Clarke were pronounced dead, and the other student admitted.

The police say the incident is related to an ongoing gang feud.
