Four days after a man fell through the ice on Lake Simcoe, police have issued a call for witnesses as they investigate the incident.

In a March 28 release, Durham Regional Police outlined the events, as they understand them, leading to the death of a snowmobiler, although they have not released his name. Family members have confirmed Ken Eastcott passed away following the rescue on Lake Simcoe.

Police say emergency services were called to Lake Simcoe at approximately 4:30 p.m. Saturday (March 24) after a snowmobile was seen falling through thin ice into the water near Thorah Island. The incident occurred about 100 feet off the southeast corner of the island.

Six people were reportedly snowmobiling together at the time when the incident occurred. One man got off his sled and jumped into the water to try and save the male. He was unsuccessful, but police say he was able to get back out of the icy water safely.

The Georgina and Brock Township Fire Departments responded and were assisted by an airboat from York Regional Police.

Eastcott, who fell through the ice with his snowmobile, was located and taken to the marina in Beaverton by airboat. He was then taken by air ambulance to a Toronto trauma centre, but succumbed to his injuries on Sunday (March 25).

A celebration of life has been set for Saturday (March 31) from 1 to 4 p.m. at the Carden Community Centre Dalrymple.

Officers would like to speak to any witnesses who were there at the time of the incident. They are asked to contact D/Sgt. Galipeau of the North Division Criminal Investigations Bureau at 1-888-578-1520 extension 2686.

The Durham Regional Police Service would like to recognize the outstanding efforts of the Brock Township Fire Department, York Regional Police, the Georgina Township Fire Department and officers from North Division for their efforts.
