A Tuscaloosa woman has been arrested after asking a Facebook friend to kill her aunt, the aunt's fiancé, cousin and the family's dog, according to court records.

The friend, however, was actually Williams' aunt herself, who had created a fake Facebook account in late May and befriended Williams. Days later, her niece was asking the online "friend" to commit the murders.

Williams, 19,  had moved in with her unidentified aunt in April, and the two frequently clashed.

Tuscaloosa County records say that Williams would invite strangers she met online to her aunt's home in Fosters, Alabama, and would go to parties with the men. The teen later blocked her aunt from viewing her Facebook activity.

Her aunt countered by creating a profile under the name "Tre 'Topdog' Ellis," and sent Williams a friend request. On the day Williams accepted the request, she also gave "Tre" her phone number and address, and invited him to get drunk and have sex with her. She asked that he pay her $50 cell phone bill in exchange.

Days later, Williams told Tre that she was angry at her aunt, and asked him to kidnap her family and the dog. The teen then gave the online friend instructions on how to get into the aunt's bedroom to murder her aunt and the aunt's fiancé, and told him to shoot her cousin and the dog as well. Williams intended to load her things in Tre's car while the killings occurred.

After reading her niece's plans, the aunt called the Tuscaloosa County Sheriff's Office. During questioning, Williams admitted to writing the instructions, but said she didn't really intend for her family to be killed. She is being held in the Tuscaloosa County Jail on a $30,000 bond.
