A sudden storm and dangerous waves capsized a 28-foot boat on Lake Tahoe last month, killing eight people, including three from New York’s Finger Lakes region, federal investigators said Wednesday. The National Transportation Safety Board’s initial report confirms the recreational vessel Over the Moon overturned near D.

None of the eight people who died following the capsizing of a boat in Lake Tahoe last month after a sunny day suddenly turned stormy were wearing life vests, according to a preliminary investigation from a federal agency.

In a horrific boating accident in Lake Tahoe in June, one survivor wore a life jacket and the other was found holding onto a life jacket, according to an NTSB report.
