EAST HAVEN, Conn. — A family member says a former Microsoft executive and his teenage son were killed when their small plane crashed into two Connecticut homes.

Blair Henningsgaard says his brother Bill Henningsgaard and nephew Maxwell were traveling the East Coast to visit colleges, and Connecticut was part of the itinerary.

He says the family learned it was his brother’s plane through the tail number.

Bill Henningsgaard was a member of Seattle-based Social Venture Partners foundation, which extended its condolences to his wife and two daughters.

The multi-engine, propeller-driven plane struck two small homes a few blocks from Tweed New Haven Airport as it came in to land.

Authorities have said as many as six people could have died in the crash, including two children in a home.
