Police investigators are trying to piece together what sparked two shootings in Rosenberg on Wednesday that left a woman and man dead and another man wounded. The first shooting occurred about 1:50 a.m. at Brittany Square Apartments in the 4700 block of Reading, according to Lt. William Henry of the Rosenberg Police Department. Investigators with the Texas Rangers, Henry said, are trying to determine if the man shot himself or if officers fatally wounded him.
