"This was an horrendous case of elder abuse," said Allen following the verdict. "He attacked the most vulnerable people, and he laughed while doing it. This was sport for him."
Ulloa was arrested Oct. 2, 2008 following an 11-month investigation by the Los Angeles County Sheriff's Department after an anonymous whistle-blower from Silverado Senior Living called the widow of 80-year-old Elmore Kittower. Kittower died Nov. 6, 2007. An investigation revealed the retired engineer had been abused for months prior to his death.
Ulloa, of Reseda, was employed as a caregiver between February and November 2007 at the facility that specializes in caring for Alzheimer's and other memory-impaired patients. All of the victims, including three men and one woman, suffered from dementia and were unable to speak or report the abuse.
Ulloa is facing up to life in prison when he returns May 26 for sentencing.
