Whitehorse RCMP have issued an arrest warrant for 32-year-old Michael Macpherson in connection with the stabbing death of Tanner Sinclair early Tuesday.

Sinclair, 27, died early this morning following an incident on Lazulite Drive in the Copper Ridge neighbourhood.

RCMP and paramedics were called to a home there at about 12:20 a.m.

Police say Sinclair was found still conscious and breathing and was taken to Whitehorse General Hospital. He later died in hospital after being admitted for treatment.

Friends and neighbours describe Sinclair as a quiet family man with a young daughter and another child on the way.

Macpherson is wanted for second-degree murder in Sinclair's death.

Macpherson is described as a Caucasian male, 5'10", 220 pounds with brown hair and blue eyes. Police say he could be driving either a 2002 Brown/Gold Cadillac Escalade with Yukon plate HHS50. or an older red Honda Civic with several dents and missing the driver’s sidedoor handle.

Police say Macpherson has connections in British Columbia and Saskatchewan and could be headed out of town.

RCMP say Macpherson is considered armed and dangerous. They ask anyone who spots him or his vehicles not to approach, but to call 911 or the Whitehorse RCMP complaint line at 667-5555.
