"Sacramento police say a 76-year-old man operating an unlicensed chiropractic clinic out of his garage is suspected of killing one of his patients with a neck manipulation.
Antonio Arellano was booked into the Sacramento County jail Friday on suspicion of murder.
Police Sgt. Matt Young says 64-year-old Jose Lopez sought help from Arellano for pain in his extremities Tuesday. Arellano adjusted the victim's neck, seriously injuring Lopez and leaving him unconscious.
He was placed on life support but was declared dead two days later.
Arellano's only apparent training was a massage class he took in the 1940s, but Young says Arellano had a following and handed out business cards in his neighborhood."
