Authorities say a man dressed as a CHP officer knocked on the door and said he needed to speak with the couple outside. When the woman and her boyfriend walked out, they saw four other people wearing dark colored clothes and blue beanies. Investigators say the woman realized something wasn't right and tried to get away.
Deputy Tom Mackenzie said, "The victim tried to flee back in the house when one of the suspects struck her in the back with what we believe was an aluminum baseball bat."
Deputies say the boyfriend started fighting with the suspects as his girlfriend screamed for help. The suspects then left.
It's not clear yet how one of the men got the CHP uniform.
