SALT LAKE CITY A Utah man accused of killing his grandmother stabbed her 111 times, telling police he had cut her in several places and removed several of her internal organs, prosecutors claim in new court documents.
Police went to 84-year-old Joyce Dexter's Salt Lake City home on Oct. 3 after receiving a domestic disturbance call. According to court records released Friday, officers found Zachary Cole Weston standing over Dexter while holding a bloody knife.
Weston had blood on his clothing and hands and later told investigators that he had "slit her belly, her heart and her jugular," the records said.
The 21-year-old has been charged with aggravated murder, a capital offense.
Family members have said Weston suffers from mental illness. He was recently charged with assault for hitting his father during a Sept. 27 argument. In 2010, he was arrested after he was accused of pushing his mother and striking a police officer. He pleaded guilty to one of two assault charges.
As part of his sentence, he was ordered to undergo a mental health evaluation and complete any recommended treatment, but he was charged Aug. 9 with two counts of assault and interfering with a police officer during an arrest for slapping one hospital employee and punching another in the face, the Deseret News reported.
Salt Lake County District Attorney Sim Gill declined to comment Friday to the Deseret News on a possible motive, but he praised police for responding so quickly.
