Police in a Dallas suburb say a former special education teacher accused of killing four people in a pair of shootings used a grenade in one of the attacks.
DeSoto police say in a search warrant released Thursday that 44-year-old Erbie Bowser detonated a grenade inside his estranged wife's house and was arrested after running out of ammunition.
The warrant says police found a grenade pin and fragments inside the DeSoto home of 47-year-old Zina Bowser.
Police didn't immediately return phone calls seeking comment Thursday.
Police say Bowser shot and killed Zina Bowser and her 28-year-old daughter on Aug. 7. The attack in DeSoto happened about 15 minutes after one in Dallas in which police say Bowser killed his girlfriend, Toya Smith, and her teenage daughter.
