ROSEVILLE-

A senior at Woodcreek High School is in a lot of trouble with police.

Roseville Police arrested 18-year-old Michael Contini for allegedly having sex with underage girls, ranging in age from  17 to 14  years old.

But, that’s not all.

“He posted some of these videos and pictures and showed some of them to his various friends. Some he emailed to other people,” Roseville Police Sgt. Jason Bosworth said.  “Some, we’re not sure if it was unknown to the girls.”

It was the work of an observant cop assigned to Woodcreek, who noticed the images on the suspect’s phone, following an unrelated arrest of Contini last week.

“If you get caught, there are some very serious consequence,” Bosworth said.

If Contini is convicted, he’d likely become a sex registrant, forced to notify law enforcement whenever he moves for the rest of his life and unable to live near schools or parks where children are present.

Investigators believe there may be other victims and they’d like to hear from them.

“He hopefully doesn’t do this to anyone in the future,” Bosworth said.
