The Harris County sheriff’s office said that deputies arriving at the soccer park Sunday morning found a 29-year-old man shot to death and his 38-year-old girlfriend wounded. Sgt. Ben Beall of the Harris County sheriff’s office said that the woman was taken to a hospital, where she and her unborn child were pronounced dead.
