Husband who had blamed cold medicine

A North Carolina man who said to himself in his wife to death on Friday.

Matthew Phelps pleaded guilty to first-degree murder for his 29-year-old wife, Lauren Hugelmaier Phelps, after an autopsy determined he had stabbed her 123 times.

Phelps, 29, will serve life in prison with the possibility of speech, ABC Durham station WTVD-TV reported.

His wife died Sept. 1, 2017, in the couple's Raleigh home.

"I have a bloody knife on the bed, and I think I did it," Matthew Phelps said in the 911 call at the time. "I can not believe this."

In that 911 call, Matthew Phelps said: "I took Coricidin cough and cold," explaining that "a lot of times I can not sleep at night."

Her body was reportedly found in the fetal position in the couple's bedroom.

Investigators said they had learned from social media that "suspect Matthew Phelps was possibly fascinated with and mimicked a serial serial killer character from the movie 'American Psycho.'"
