NEWPORT, Ore. -- Three people including two teenagers in the coastal town of Newport are accused of “sexting” and it could put them behind bars.

Dave Simpson, 30, and two teens face years behind bars in connection with cell phone video of a teenage girl in a sex act. Newport Police say last spring in a vacation rental, a night of binge drinking went too far.

The police report alleges three people took advantage of a 17-year-old drunk girl.

Police say Simpson forced his dog to perform a sexual act on her while a friend recorded it on her cell phone. According to detectives she did it because it was funny. She then shared it with 18-year-old Jesse Carey, who sent it to some friends.

“She’s handled it really well. But because of this situation I think she’s had some problems,” the girl’s principal Jon Zagle said.

But is this a prank or pornography?

It has the coastal city talking.

“I wonder what that 30-year-old man was thinking,” Newport resident Chuck Victory said. “What is he doing with those kids?”

Prosecutors aren’t saying, but it’s raised the question as to whether “sexting” should be a crime punishable by prison time.

If convicted, Simpson and the two teens involved face years in prison and would have to register as sex offenders.

One of the accused is also the son of a local sheriff’s deputy. A Benton County prosecutor is handling the case.
