Authorities have identified a man whose death on the Sunshine Coast last week was deemed suspicious and are appealing for witnesses and information in hopes of advancing their investigation.

Henry Doyle, who is 58 and from Vancouver, was found injured near Klein Lake in Egmont on Sept. 23, according to a statement from the Integrated Homicide Investigation Team.

"First responders arrived on scene and provided emergency first aid, but sadly, the victim succumbed to his injuries," IHIT said in a statement. "The man’s death was determined to be suspicious in nature," adding that the coroner consulted with police.

Police say they have learned that Doyle travelled to the area on his dirt bike, which was found near his body. Police have not revealed how Doyle suffered his injuries or why his death is being considered suspicious.

CTV News has learned Doyle owned a Canada-wide dental service provider and also served as president of the Dental Industry Association of Canada.

“We are shocked and saddened by the sudden death of Henry Doyle,” read a statement from the non-profit's board of directors. “Henry was an esteemed leader in the Canadian dental industry and his death is a great loss to all who knew him.”

The Pacific Dental Conference also told CTV News it is deeply saddened to hear of Doyle’s death.

Investigators say they want to speak with anyone who was in the Klein Lake area last Friday, urging them to call the IHIT Information Line at 1-877-551-IHIT (4448).
