Sheriff's deputies found a man and woman dead on the floor of a Bardwell home at about 11:30 p.m. Another man found lying in a hallway had life-threatening injuries and was rushed to a Dallas hospital where he later died.
    
The victims' names have not been released.
    
Costilla remains in a detention center. It was not immediately clear if he had an attorney.
