According to a member of the group, Monge got close to Sorensen and was either pushed off her bike or she ran into him and fell off. Sorensen allegedly knocked Monge's phone out of her hand and that is when she started swinging at the victim. The husband also joined in on the fight, the complaint said.

His two friends pulled the couple off Sorensen and they allegedly fled on their bikes.
