The autopsy report for a Texas man who killed his former daughter-in-law and another woman at a Delaware courthouse shows he had a brain tumor.
The report notes a large tumor known as a meningioma was found during the autopsy.
Authorities say 68-year-old Thomas Matusiewicz killed himself following the courthouse shooting Feb. 11. The gunman's widow, Lenore Matusiewicz had sought an independent autopsy saying she believes an untreated brain tumor was to blame for her husband's violent actions.
Matusiewicz was cremated shortly after his body was released by the state. The Delaware attorney general's office had initially refused to allow the release of the autopsy to the family, citing an ongoing investigation.
The shooting capped a years-long custody battle between Matusiewicz' son and his ex-wife.
David Matusiewicz faces a hearing April 23 on charges he violated his probation by failing to stay away from guns and lying about his whereabouts and activities.
Matusiewicz, 45, pleaded guilty to fraud and kidnapping charges in 2009 after taking his three daughters to Central America. He was arrested on the day of the courthouse shooting.
