WILMINGTON, Del. (AP) — A 68-year-old man whose son was engaged in a bitter custody battle was identified Tuesday as the gunman who opened fire in a Delaware courthouse lobby, killing his former daughter-in-law and another woman. The gunman also died after exchanging fire with officers.

Delaware State Police said Thomas Matusiewicz of Edcouch, Texas, shot 39-year-old Christine Belford and her 47-year-old friend Laura Mulford on Monday. Two police hit by gunfire were protected by their armored vests.

Police were awaiting autopsy results Tuesday to determine whether Matusiewicz was killed by police or shot himself with his .45-caliber semiautomatic handgun.
