A man who used to live in Alexandria, Va., filmed unconscious women and sexually assaulted some of them, according to police.
Joseph M. Rivera, 34, formerly of 724 Four Mile Road, was arrested Tuesday in Las Vegas after an investigation by Fairfax County and Alexandria police found he allegedly filmed several women without their consent or knowledge and stored the videos on electronic devices.
A concerned relative of one of the victims notified police in May.
In a search warrant filed in Fairfax County Circuit Court May 13, Detective Brian J. Byerson wrote all the victims appeared unconscious and were unaware of the videos and photographs, The Washington Post reported.
Police said all of the women were adults and most of them in their 20s, according to the Post. Some have been identified, but police said they are working to identify others.
It's unclear how the women became unconscious, and police have not yet released a number of potential victims.
News4's Erika Gonzalez spoke with Rivera's former co-worker Wednesday evening. The two instructed minors.
"He did come across as creepy and and made some of the female co-workers uncomfortable, from what I was told by them," the man said. "He invited drunk women back to his apartment."
Rivera worked as a party disc jockey and hosted bartending competitions across the region, police said. Police did not say whether he met victims through his job.
He is believed to have left the area in June and has confessed to the crimes, police said.
