Man who said he heard demons before killing grandmother sentenced to life in mental health facility

JANESVILLE, Wis. — A man who admitted to killing his grandmother after claiming he saw and heard demons could spend the rest of his life in a mental health institution.

Rock County Judge Barbara McCrory ordered 37-year-old Jamie Beggs to be committed for the rest of his life, but with the possibility of being released after at least 25 years. If Beggs were ever to be released from the mental health facility, he would be under parole for the rest of his life.

“It’s a lifelong battle for you and it’s been a battle that, unfortunately, you’ve been losing for a while,” Judge McCrory told Beggs during his sentencing hearing Wednesday. “This is your opportunity to address it. This is your opportunity to continue to move forward.”

Beggs has been diagnosed with bipolar schizophrenic disorder, as well as a personality disorder and substance abuse disorders. He was previously admitted to Mendota Mental Health Institute after reporting hearing voices.

He pleaded guilty earlier this month to killing his grandmother, Kathleen Beggs, last summer in the Town of Center in what prosecutors and investigators called an “extraordinarily violent case.”

Jamie Beggs reportedly said there were demons in his head and asked someone if they could see the demons before saying his grandmother was in the garage, where her body was found.

Beggs reportedly told police his grandmother was a martyr, and her death would give her sainthood. He says he was allegedly hearing voices and seeing demons for 6 to 8 months before he killed her.
