Prosecutors are waiting for autopsy results to determine if abuse and neglect contributed to the death of a 64-year-old woman last week.
Ruthann Jacox died at Tucson Medical Center Nov. 8, 11 weeks after her caregiver, Lea Marie Hughes, was arrested on suspicion of vulnerable adult and child abuse charges.
"Based on the fact Ms. Jacox was the victim in an ongoing elder-abuse case, we requested an autopsy to determine if the abuse was a contributing factor in her death," said Assistant Arizona Attorney General Jesse Delaney.
Jacox invited Hughes, her boyfriend, Gilbert Pierre Peralta Jr., and two minor children into her east-side home five years ago because Jacox had multiple sclerosis and needed help, according to court testimony and Delaney.
Peralta, 39, was arrested Tuesday on suspicion of fraud, fraudulent use of a credit card, theft of more than $25,000, vulnerable physical adult abuse, emotional abuse, unlawful imprisonment and permitting the life of a vulnerable adult to be endangered by neglect. He was released from jail Wednesday under the supervision of Pima County's Pretrial Services agency.
