The affidavit said the injuries were reported to state police by a Franklin County Area Agency on Aging worker who visited the home later that day. Police served the warrant on Sunday.
Mayetta Elliott, 81, told authorities her assailant "shook the daylights out of me," according to the affidavit. The man was irate because he thought she was responsible for cutting water off to his livestock, the affidavit alleged.
The report said Elliott was arrested without incident at about 3:30 p.m.
Ronald Elliott was convicted by a jury in 1996 on charges of aggravated assault, recklessly endangering another person, simple assault and making terroristic threats in an assault on his father, the late Jacob Orvall Elliott, according to court records. Those incidents occurred between April 1 and April 9, 1995.
Ronald Elliott was sentenced to four to 23 months in the county prison, but court records said he is appealing the conviction and has not served the sentence.
Mayetta Elliott was in court Monday for a protection hearing. Her attorney, Lynn MacBride, said a petition was filed by the Area Agency on Aging, which has had Mayetta Elliott under its care recently at the Franklin County Nursing Home.
"His order was that she be able to return home when possible," MacBride said of Judge Richard J. Walsh's order at the hearing. She declined to go into details about the case, but said, "It has nothing to do with any charges as far as Ronald is concerned."
