Steven Rogers, 25, made his first court appearance Friday morning on the charge.
Police say Rogers and Collett knew each other and the attack was not a random incident.
Integrated Homicide Investigation Team Staff Sgt. Jennifer Pound says police arrested Rogers the day after Collett's alleged murder.
"To have charge approval, only days following a homicide, speaks to the success of an integrated unit," she said, adding that there was strong cooperation between IHIT and the New Westminster Police Department.
Collett a night shift support worker
Collett worked as crane operator by day and as an evening support worker at Last Door's adult program according to the centre. He was also a certified search and rescue volunteer.
Last Door Recovery says the facility in the 1100 block of Nanaimo Street is a transitional living residence for clients who have completed five months of primary care treatment.
It has been operating in New Westminster for the last 30 years and says it has never before experienced this kind of an incident.
Collett had been at the recovery home since April 2012.
