UPDATE: Prom party murder suspect turns himself in

Police say two teens have been charged with murder in a fatal shooting at a prom after-party north of Toronto last week, while a third faces a related charge.

York Regional Police say 18-year-old Jahdea Paterson of Toronto and a 17-year-old boy who can't be identified are charged with first-degree murder, while a 16-year-old is charged with being an accessory.

Eighteen-year-old Rizwaan Abookbabar Wadee of Vaughan, Ont., was found dead at a large house in Whitchurch-Stouffville, that police say had been rented out for an after-prom party.

In a news conference this morning, Inspector Thai Truong said approximately 400 people had attended the party, but no one stayed behind after police were called.

Police say Paterson turned himself in Wednesday night and is due in court in Newmarket, Ont., today for a bail hearing.

The 17-year-old and the 16-year-old, who also face firearms charges, were taken into custody shortly after Wadee was killed.
