Taylor Swift trial against former Denver radio DJ starts next week

DENVER (KDVR) -- More than four years after a former Denver radio DJ allegedly grabbed pop star Taylor Swift from behind, the case is going to trial in Denver.

Here's what we know.

What happened?

Swift was in Denver on June 2, 2013 for her Red Tour at Pepsi Center. During a meet-and-greet before the concert, Swift says she was grouped by David Mueller, who was known on the radio as “Jackson” on 98.5 KYGO.

According to court documents, Swift says Mueller “put his hand under [her] dress and grabbed [her] bare (behind).” Swift said that she became “shocked and withdrawn” following the incident.

A photo of the incident was obtained by TMZ.

Mueller says he did not inappropriately touch Swift.

KYGO fired Mueller two days later for “violating the morality clause of his contract after it independently determined that he had lied about the incident.”
