Dallas police don’t have much to say about the shooting death of a man in his Red Bird-area home. At about 3:30 p.m. Monday, neighbors heard gunfire and called 911. When police went into the home on Greenspan, near I-35 and Camp Wisdom, they found the man gravely wounded. He was pronounced dead a short while later at Parkland. Homicide detectives have no information about the killer or any possible motive.
