SAN ANTONIO (AP) - Authorities say a man accused of killing his ex-wife and her brother at a relative's San Antonio-area house later went home and fatally shot himself.

Bexar County sheriff's Detective Louis Antu said 47-year-old William McKendrick died at a San Antonio hospital Thursday, a day after the attack.

Family members told the San Antonio Express-News that the suspect and 48-year-old Sonya McKendrick had recently divorced and he was angry she was trying to move on.

Officials say the two began arguing outside her parents' home, where William McKendrick went to pick up their 7-year-old son Wednesday night.

Deputies said the man chased his ex-wife inside, fired several times at her and gunned down Melton Lozano Jr., her 57-year-old brother, when he tried to help.
