A manhunt is underway in Texas for a gunman who killed five people at a home near Houston. The San Jacinto County Sheriff's Office says the suspect is still on the loose and is believed to be armed with an AR-15 semiautomatic rifle. Authorities say an eight-year-old child is among the five people found shot to death last night in the town of Cleveland. Police identified the suspect as a Hispanic male described as a neighbor of the victims.
