Dawn Marie Viens, 39, was last seen on October 18, 2009, leaving the restaurant she ran with her husband, Thyme Contemporary Cafe in Lomita, California. Her husband David Viens initially told investigators she had left after an argument and that she had previously gone missing, but he later became the prime suspect.

In 2011 David Viens confessed that an argument led him to restrain Dawn with duct tape and that she choked on her vomit while restrained. He said he then disposed of her body, later admitting he had cooked her remains over four days in a 55-gallon drum and discarded them in the restaurant’s grease pit and trash bin. Despite searches, Dawn’s remains have never been recovered.

David Viens was convicted of second-degree murder in 2012 and sentenced to 15 years to life. Did anyone who knew Dawn or worked at Thyme Contemporary Cafe notice anything unusual in the days after October 18, 2009?
