Woman Who Accused 'Teen Mom' Amber's Fiancé Of Sexual Assault Committed Suicide Months After Alleged Attack

A sexual assault scandal surrounding Teen Mom OG star Amber Portwood's fiancé is marked by tragedy.

As RadarOnline.com exclusively reported, a young woman accused Matt Baier of sexually assaulting her in a 2014 restraining order against the 44-year-old Boston native.

And now, in a horrific twist, RadarOnline.com can reveal that the alleged victim died just six months after slapping Baier with protective papers.

The woman— whom RadarOnline.com has chosen to call Michelle in lieu of her real name for privacy reasons— committed suicide in November 2014, her mother confirms.

Michelle was "frightened" of Baier following the alleged incident.

After learning Baier told her "all kinds of lies" in addition to his alleged sex assault, Michelle ended the relationship, a source recalls. "She did some research on him, and found out a lot of what he told her wasn't true. She left, and filed a restraining order to protect herself."

She passed away in November of that year.

A source close to Baier vehemently denies he assaulted Michelle, and claims he was never even questioned by police.

"He did not keep in touch with her, and did not know she had passed away," the source tells RadarOnline.com.

Portwood, 25, the mother of 7-year-old daughter Leah, has defended her man through his recent scandals, including RadarOnline.com's report that he secretly fathered eight children.
