Authorities say an aircraft passenger who died last weekend when a small plane crashed into a swimming pool in southern Illinois has been identified.

Centralia police say 56 year old Cheryl Monserat-LaGreca of Lacon, Illinois, near Peoria died on impact Saturday when the Beechcraft A35 aircraft crashed less than a mile from the Centralia Municipal Airport.

She was the plane’s only passenger. The plane’s pilot, Peoria-area resident Glenn Rossi, was airlifted to a nearby hospital after firefighters and others freed him from the plane’s wreckage in the ruins of a backyard swimming pool.

The Federal Aviation Administration is investigating the crash.
