SAN ANTONIO - San Antonio police believe the discovery of two men and a woman shot to death in a house is a double murder and suicide.

Police received a call Thursday morning from authorities in New Ulm, Minn., asking for help checking on a truck-driving team that hadn't reported in more than two weeks.

Officers who arrived reported hearing sound from a television, looked through a window and saw a man dead in a chair.

Once inside, police discovered another man dead on a bedroom floor and the woman wrapped in a blanket in another room.

Names of the victims haven't been immediately released. A police report identifies the man in the chair as 76 years old, the woman as 67 and the third victim 45. Their relationships aren't immediately disclosed.
