Executive at Boston capital investment firm, daughter are killed in Milwaukee plane crash

The victims of a plane crash in Milwaukee have been identified as the chief operating officer of a Boston capital investment firm and his daughter.

Summit Partners said in a statement Thursday that the victims of Wednesday's crash are Joseph Trustey and his daughter, Anna.

They were traveling to the Midwest for a college visit.

Federal investigators will try to determine why the single-engine plane crashed and erupted in flames at Timmerman Airport on Milwaukee's northwest side. Neighbors whose houses border the airport witnessed the crash at about 6 p.m. but say the flames and smoke made it impossible for them to help.

Witness Ken Gipp says the plane was flying very low when the right wing hit the ground and a wall of flames ignited.
