EAST HAVEN, Conn. (AP) — One of two Connecticut homes that were struck by a plane two weeks ago in a deadly crash is set to be demolished.

Crews are expected to tear down the house in East Haven on Thursday. Mayor Joseph Maturo Jr. says all necessary approvals were obtained and environmental testing has been done.

No one was in the house that is being demolished when a 10-seat airplane crashed Aug. 9 while approaching Tweed New Haven Airport.

A 13-year-old girl and her 1-year-old sister were killed in the neighboring home. Officials say that house will be torn down soon.

Two people in the plane also died: former Microsoft executive Bill Henningsgaard of Medina, Wash., and his 17-year-old son.

The cause of the crash remains under investigation.
