From Colorado, Catherine St. Germain posted a video of herself holding up notecards. The cards tell the story of her 15-year-old daughter's sexual abuse at the hands of Catherine's now-ex-husband.
Catherine, via cards, urges single mothers to check the sex offender registry to ensure their families are safe.
"Monsters look and act normal. They are very good at hiding who they really are," she said and added, "They are the people we trust with our kids every day. All single moms should check the National Sex Offender Registry."
On her personal Facebook page, she posted the video last Friday. Today, the video has been viewed more than 50 million times.
"I ask that you share this short video. I believe we must not remain silent, and instead shine a light in this dark subject", she wrote on her page.
As per media reports, Catherine's ex-husband only received a 90-day jail sentence and eight years of sex offender probation.
