Text messages and incriminating online chats show that a 30-year-old woman had a longterm sexual relationship with a 15-year-old boy, cops said.
Tanner Vicory is accused of having sex on at least ten occasions with the teen brother of her boyfriend, according to the Arizona Republic. Her boyfriend was in prison at the time.
The teen's mother became suspicious when she found a text message on her son's phone from Vicory saying that she loved him.
ABC 15 reports that Vicory was arrested at her Gilbert, Ariz. home last Friday for the alleged relationship, which authorities said took place between November 2011 and April 2012.
"If something feels uncomfortable, you need to head it off at the pass," Gilbert police Sgt. Bill Balafas told ABC 15. "You always need to know where your kids are. As parents, we need to be on-guard 24-hours-a-day with our children."
Vicory is charged with sexual conduct with a minor, according to KFYI.
Police said they do not suspect there are other victims.
