When police arrived, they found Jost on the ground with "a laceration on the back of her head" and "blood coming from her nose and mouth," a charging affidavit says. An autopsy was planned to determine exactly how she died.
The problems started, witnesses told police, when Lamothe arrived and hugged Jost from behind, grabbing her breasts. She told him to "get off of her," according to the affidavit, and Lamothe was told to leave. Lamothe started a brawl, police said, then left the bar.
He later returned and threw the fatal punch, police said. Lamothe hit Jost in the face with a closed fist, knocking her down, according to witnesses.
A police spokesman said he wasn't charged with murder because "we can't prove anybody knew the punch would cause her to fall and hit her head."
