Sahuarita police Monday arrested Edward Villa, 63, on a charge of homicide in the death of a Sahuarita woman, Robin Satinsky, 89.
He was booked into the Pima County Jail. Bail was to be set at his first court appearance at 8 p.m. Tuesday.
Satinsky’s decomposed remains were found June 6 along Interstate 19, south of Pima Mine Road, said Sahuarita police spokesman Officer Sam Almodova in a news release.
Almodova said DNA evidence linked Villa to the killing. He did not provide details on where and when Villa was arrested.
He said Villa had befriended the woman and done some type of work for her.
Authorities first got involved in what appeared to be a missing person case after Satinsky’s family said it was unable to reach her, and asked for a “welfare” check on Nov. 5.
A police officer determined she hadn’t been seen for “an unusual amount of time” and the welfare check turned into a missing person case.
Villa, who gave jail authorities a general delivery address, said he was employed by Labor Finders, 6418 S. 12th Ave., a day labor business.
