A 34-year-old man who inexplicably bit a 14-year-old girl on the breast during a Green Day concert at Portland’s Moda Center was sentenced Monday to 30 days in jail.

Joel Brian Dauncey of Vancouver, B.C., was standing next to the girl during the Aug. 2 concert when he leaned over and bit her. He didn't know her. The girl immediately told her mother, who was standing on the other side of her.

The bite left no bruising and didn't break the skin. The girl described her pain as a "3" on a scale of 1 to 10, with 10 being the most painful, according to a probable cause affidavit.

Dauncey, who appeared in Multnomah County Circuit Court wearing a blue jail uniform, offered no reason for his behavior. He also made no statements. But his defense attorney, Joseph Westover, said his client “very much regrets what happened.”

Dauncey was noticeably drunk at the time. A worker at the Moda Center had cut him off from buying more alcohol and a security guard told police she was keeping watch on Dauncey for that reason, according to the affidavit.

The guard saw Dauncey bite the girl’s breast. Police also noted that Dauncey appeared intoxicated.

Dauncey told investigators he doesn’t remember biting the girl, said prosecutor Melissa Marrero. He pleaded no contest to misdemeanor harassment of a sexual or intimate body part.

The crime isn't a sex offense and won’t require Dauncey to register as a sex offender, but the prosecutor said her office and the victim’s mother were satisfied that Dauncey’s conviction record will show his crime was sexual in nature.

“When this case came in, of course, we took it extremely seriously,” Marrero said.

Neither the girl nor her mother attended Dauncey’s plea and sentencing hearing.

Dauncey has no prior criminal history.

He told authorities that he was employed full time as an operator for a computerized sign company. Shortly after his arrest, he said he was “fairly certain” he no longer had a job.

Dauncey told authorities that he drinks once a week and uses cocaine once a month.

Several friends and family members wrote letters to the judge, vouching for Dauncey’s character.

In court, Dauncey’s father stood up to tell the judge: “Joel’s a great guy. ... Not a mean bone in his body.”

“It was an unfortunate incident, never to be repeated I’m sure,” said his father, who didn't give a name.

Circuit Judge Angel Lopez responded: “It’s more than that. It’s a serious crime.”

In approving the plea agreement for 30 days jail and 11 months of probation, Lopez told Dauncey that the sentence would have been a lot tougher if Dauncey had broken the girl’s skin.

“We all have the right to feel safe in public,” the judge said. “I don’t think this young woman is going to feel safe in public for years to come because of your outrageous behavior.”

Dauncey has been locked up since his arrest Aug. 2 and is expected to be released from jail almost immediately for time served.

The judge said Dauncey's sentence was “well deserved.”

Dauncey’s sentence doesn’t prohibit him from living in the United States, although Dauncey has said he has no ties to Portland and was only visiting from Canada so he could attend the concert.

While on probation, Dauncey must obey all laws and refrain from using illegal drugs. The judge also prohibited Dauncey from drinking alcohol while on probation or working at bars or other businesses that primarily focus on alcohol.

“I strongly, strongly recommend that you never take another drink again,” the judge said, “because ...it could have been a lot worse.”
