Police said the woman was waiting for a phone call in her car when a man, whom she didn't see, punched her in the face a couple of times.

"I hear a lady crying and screaming help or something and there's some guys across the street," the caller told dispatchers in the 911 calls released on Wednesday. "She was yelling leave me alone and she's yelling and screaming and a gentlemen just walked out of the house again. I think he's waiting for the other guy to come back."

"And the guy is coming back to the house messing with her," the caller said. "Unbelievable."
