Was This Grandpa Falsely Accused Of Molesting His Grandson?

About two years ago, a policeman knocked on Betty's door, she says, alleging that her husband of 23 years, Bill, had inappropriately touched their 5-year-old grandson.

"Bill was arrested on the spot and taken to jail," she recalls. “Police charged Bill with child molestation, and my husband spent two weeks in jail. I went ballistic. I knew there was no way in the world Bill has ever laid a hand on our grandson. It's all lies ... It was horribly devastating."

In the video above, Bill calls his grandson "sexy butt" several times and pinches him on the butt — a video that Betty believes is "not incriminating at all."

"The prosecutor said they could prove that was a lustful video on Bill's phone,” Betty says. “The prosecutor did claim that that was child abuse.”

A few weeks ago, Bill reached a plea deal, pleading no contest to two counts of felony child abuse. He is now a registered child abuser.

"My husband has been falsely accused,” Betty says through tears. “My husband has done absolutely nothing wrong, and this has completely destroyed our lives."
