Luella McAdoo is a longtime family friend of the victim, according to Tampa police spokeswoman Andrea Davis.
On April 5, the man's mother left him in McAdoo's care while she ran errands. When she came home at about 6 p.m., she found her son performing oral sex on McAdoo. The woman told McAdoo to go home, then she called police because her son, 34, does not have the ability to make a decision about sex on his own, Davis said.
The investigation, Davis said, was particularly challenging because of the victim's mental condition and inability to communicate verbally.
After the detectives investigated, according to Davis, they direct filed the case with the State Attorney's Office, who filed charges.
McAdoo was arrested at her 953 Chestnut St. W home this morning by Hillsborough County Sheriff's Office deputies on a Tampa police warrant, according to the Hillsborough County Sheriff's Office. She was charged with lewd or lascivious battery on an elderly or severely disabled person and is being held at the Orient Road Jail on $7,500 bond, according to jail records.
