In the hit documentary Making A Murderer, Steven Avery is portrayed as a harmless, simple man whose skirmishes with the law prior to being convicted of a brutal rape and murder are chalked up to youthful idiocy.

The film notes that he was involved in a few burglaries, burned a cat alive , and ran his female cousin off the road in a fit of rage. But for the most part, theres nothing offered by the filmmakers to suggest he had a history of violence against women.

In a new interview, however, Averys ex-fiancee Jodi Stachowski says he was a violent and abusive "monster" who strangled her and threatened to kill her during their two-year relationship.

"He'd beat me all the time, punch me, throw me against the wall," Stachowski told HLN on Wednesday. "He's like Dr. Jekyll and Mr. Hyde."

Records from the Manitowoc County sheriff's department obtained by The Huffington Post confirm that police responded to domestic incidents involving Avery and Stachowski, as well as his former wife, Lori.
