A 3-year-old boy died after being shot at a southern Dallas apartment complex early Sunday, and police are investigating the circumstances surrounding his death. Officers were called to the complex on Wadsworth Drive, near Loop 12 and Interstate 45, at about 1 a.m. Oct. 11, according to the Dallas Police Department. They found the child unresponsive with an apparent gunshot wound and took him to a hospital, where he was pronounced dead. Police have not provided details about how the child was injured. The motive and circumstances remain under investigation, the department said. Neighbors who said they knew the family described the loss as heartbreaking.
