Keith White, 34, ID'd as man overboard on Lake Ontario party boat

Keith White has been identified as the man who fell overboard on a party cruise in Lake Ontario on the weekend.

White fell off the Mariposa Cruises ship Northern Spirit near the Humber River on Saturday night, police reported. A search for the man has been ongoing since. 

White's family released a statement Monday that says the family is confused how White, who they say is a certified lifeguard, ended up in the water.

A foggy morning and strong currents near the Humber River are complicating search efforts, according to Sgt. Gerry Klunder of the Toronto Police Marine Unit. 

Police say they're still investigating the circumstances of the incident.
