New Mexico man arrested after allegedly dismembering and disemboweling wife ahead of Thanksgiving dinner

Relatives reportedly told police Denio was diagnosed with frontotemporal dementia two years ago

A family's Thanksgiving festivities took a turn after a New Mexico man was arrested Thursday after allegedly stabbing his wife to death and dismembering her body. 

Relatives had found Karlan Denio, 62, lying in bed with his wife Connie's body on the floor ahead of the family's Thanksgiving meal. They then called police and Denio was taken into custody Thursday afternoon and charged with first-degree murder, according to a criminal complaint obtained by the Albuquerque Journal. 

Denio's brother was the first to arrive at the Denio home ahead of the family dinner, where he found he was unable to get inside and was unable to get in touch with Denio. He then called his sister who contacted local authorities about the strange circumstances. Police notified the siblings they could not force their way into the home. 

The siblings then drove to the Denio home together, where they tried knocking on doors and windows while they waited for police to arrive, according to KOB4. They were finally able to enter the home via the garage.
