A man from Minnesota has been arrested for killing his grandmother with a hammer after she blew her nose during dinner. Eighty-four-year-old Agnes Wagner-Steele was unconscious and dead after being beaten to death by her grandson, her daughter and mother of the suspect said, according to the District Court's Statement of Probable Cause.

Timothy Robert Steele, 36, has been charged with second-degree murder in relation to the Oct. 15 in a house in Farmington.

"I killed my grandmother," Steele said in his statement. "Two maybe three hours ago," he answered when asked about when he committed the crime, The Smoking Gun reported. 

After his rights were read, Steele mentioned that he was disconcerted thinking that his grandmother made a hole in one of his jackets and when she blew her nose during dinner. He said after dinner he was still too gripped by the idea of feeling mucus in his mouth and that the smell still lingered. He thought that killing his grandmother would make the feeling go away, the statement added. He then pounded her seven to eight times using a hammer.

Steele said that he heard voices in his head telling him to commit the crime and even said he was a "terrible criminal" after he did it. He wanted to kill himself as well but was advised otherwise by his mother who then called 911, according to Crime Feed. 

Steele first appeared in court on Monday and had bail set at $750,000 without conditions, whereas a $500,000 bail has conditions. If proven guilty of the crime, Steele can face up to 40 years in prison, according to CBS.
