Dover, DE -- Delaware police say several firearms and ammunition were found inside a car owned by a man who killed his former daughter-in-law and another woman at the New Castle County Courthouse before killing himself.
A search warrant affidavit says the guns were found Monday in a Honda registered to 68-year-old Thomas Matusiewicz and parked at a home in Elkton, MD, where Matusiewicz, his wife and son spent the night before Monday's shooting.
Police also said 45-year-old David Matusiewicz had a key to his father's car, which was seized Tuesday.
Nobody answered the door at the Elkton home Friday. A Maryland judged denied a request by The Associated Press to release a search warrant executed by Maryland police.
