A Juneau man has been arrested for assaulting his 79-year-old relative, the Juneau Police Department said.

According to JPD, witnesses told police that 53-year-old Kevin Willis assaulted the older man on Oct. 16 in his home on Lemon Creek Road. Police said Willis and the 79-year-old are related by adoption.

"On [Oct. 19], at about [1 p.m.], the emergency room at Bartlett Regional Hospital reported to JPD that a 79-year-old male Juneau resident had come into the ER with significant injuries related to an assault," the police wrote in a statement. "Most of the male's face, head and neck were black and blue; both arms and legs had extensive bruising and there was a large open wound on his right arm."

Police said the man had bruises on his chest, stomach, back and inner thighs. He also had a large, open wound on his leg that became infected.

According to police, emergency room staff said the assault could have been life-threatening because of the man's age, prior health condition and lack of medical care after the incident.

JPD said officers served a search warrant at the older man's home.

"The search warrant was to look for evidence of the assault, and because the suspect was believed to be living there," police said.

According to JPD, witnesses told officers they thought Willis would have killed the 79-year-old if they hadn't stopped him. Police said they found blood in the residence on carpet, walls and furniture in the bedroom where the assault allegedly happened.

The officers found Willis at the home and placed him under arrest for second-degree assault related to domestic violence. Police say Willis was taken to jail and held without bail.
