Brunner told police that she had fallen at least a day before the Feb. 19 emergency call and that he didn’t try to help her.
He was his mother's caretaker, Raleigh's News and Observer reported.
"Based on his statements that she was moving or 'squirming,' it is believed that she was alive for some time after falling," police said in the search warrant application, WRAL reported. "Mr. Brunner admitted to investigators that his mother was alive and made attempts to communicate with him for some time after falling, however, he willfully failed to assist her. He further admitted that he knew his inaction would likely lead to her death and that he wanted her to die."
Brunner told police that he thought that after she died, he'd be able to access $30,000 in her bank accounts, WRAL reported.
The News and Observer reported, however, that Brunner already had control of at least part of her money and handled her finances.
