Ontario's Special Investigations Unit has confirmed a body found in an Ottawa river last week is that of Calgary resident Muhab Sultanaly Sultan, wanted in the death of a teenager who was trying to reclaim his cellphone.

Sultan, 23, was wanted for second-degree murder. Jeremy Cook, 18, of Brampton was shot and died in a London, Ont., parking lot on June 14 while trying to track down the lost cellphone.

On Saturday morning, the body of a man was pulled from the Rideau River after it was spotted by a member of the public, ending a two-day search that began last Wednesday, after a man allegedly used his vehicle to try to run down two Ottawa police officers on bicycles in the downtown area.

A police cruiser chased the man's vehicle, but the driver was able to get away. Hours later, however, police received a number of calls from residents about a suspicious man near Range Road and Mann Avenue.

The man attempted to swim across the Rideau, and when he began showing signs of distress, two officers jumped into the river to rescue him. As the officers got closer, the man disappeared under the river's surface.

Cellphone chase ends in death

Cook had inadvertently left his cellphone in a taxi, and had used a mobile-tracking app to trace it to an address in London's north end.

Police have said that Cook was confronted by three men in a car when he arrived at the address. When the vehicle tried to drive away, Cook grabbed on to the driver's side door. Shots were fired and Cook died from multiple gun wounds, police say.
