Mystery lingers in how Prince Rupert man died

Police are still trying to determine if foul play was involved in the death of a Prince Rupert man in March.

The body of Justin Brooks, 21, was found along the shoreline of the Rotary Waterfront Park on March 4.

An autopsy found that Brooks had drowned, and that his body had no obvious signs of other serious injuries that would have caused his death.

RCMP Const. Lesley Smith says there was a gathering at the waterfront the night Brooks died, and alcohol may have been involved.

She says the shoreline was also very slippery that night.

"We're looking at so many different factors. We're speaking to the witnesses. What transpired before everybody went home? [There are also] the environmental factors: Could Justin have gone out onto some rocks and slipped and fallen? All these are being taken into account," Smith said.

Smith also said false information has been circulating on social media sites, and the speculation could end up hindering the investigation.

Investigators are still waiting for the final toxicology report from the B.C. Coroners Service.
