(CNN) A Dallas resident who fatally shot a backyard intruder and then went back to bed has been charged with murder, according to police.

The homeowner, James Michael Meyer, said he didn't know whether he struck the person, so he went back to bed and didn't call police, according to an arrest warrant released by the Dallas Police Department.

Meyer, 72, says that he was awakened around 5 a.m. Thursday by a noise outside, according to an arrest warrant affidavit filed by Dallas police. Meyer told police he looked outside and saw someone attempting to break into his storage shed, and that's when he got his handgun and went outside to confront the person.

Meyer told the intruder not to come any closer or he would shoot him, the warrant reads. Meyer said the man took a few steps toward him with a pickax in his hand, the warrant says, and that's when he fired his gun. He said the unidentified man dropped the pickax and ran into the park behind his property. Meyer told police he fired another shot "into the night" in the direction of the park and then went to bed.

As the sun began to rise, Meyer looked outside and saw what he thought was a black bag in the park. He went to get a closer look, according to the warrant, and discovered a man lying facedown on the ground.
