Bristol Palin Describes Moments That Led to Drunken Brawl

Bristol Palin said the drunken brawl involving her family at a house party last month was started when she was defending her younger sister, newly released audio reveals.

The eldest daughter of Sarah Palin is heard on the audio obtained by ABC News from the Anchorage Police Department sounding extremely upset as she describes the fight, and telling police that her "5-year-old [is] in the car!"

She can be heard telling an officer that her sister Willow, 20, came up to her while she was waiting in the family's rented limo and told her an "old lady" came up to her and "pushed" her.

Bristol Palin told the police she responded, "Oh f****** hell no, no one is going to touch my sister."

Palin, who was described in the previously released police report as "heavily intoxicated and upset," tells the officer that when she confronted the woman, a man "gets in my face, pushes me down on the grass, drags me across the grass" and swore at her, calling her a "slut," among another names.

She then says she was pushed down again and pulled by her feet by the man who "comes out of nowhere," identified in the earlier police report as Korey Klingenmeyer, who owned the home where the party was held.

Palin says she doesn't know the man and has "never seen this guy in my life."

Prosecutors said earlier this month they would not proceed with charges in the fight. The police were called to a birthday party for twin brothers Matthew and Marc McKenna at Klingenmeyer's home in South Anchorage on Sept. 6. It was also Todd Palin's birthday, who also attended with his wife and children.

Klingenmeyer told officers in the police report that Bristol Palin punched him five to six times in the face and that she was "hitting pretty hard."

An officer wrote in that report that both Sarah and Todd Palin "appeared upset and in a verbal argument with other individuals at the scene." There is no interview with the former Alaska governor and 2008 GOP vice presidential nominee included in the report, but she is heard in the background of the audio. The existence of the audio was first reported by TMZ.

Klingenmeyer, who is described as "moderately intoxicated" in the report, told police he was considering filing charges and was "angry that the Palins had showed up and were causing problems," according to the same report.

He told police he had asked Bristol Palin to leave and she responded, "Who the f*** are you?" Klingenmeyer told her he owned the home and Palin said she didn't believe him and "she will kick his a**," the police report says.

The report also includes accounts of a fight that Track Palin, Sarah and Todd Palin's eldest son, allegedly got into at the same party.

Palin's representatives did not immediately respond to a request for comment.
