“We of course are deeply saddened and disturbed that one of our officers acted in such a reprehensible manner,” Chesterfield Police Chief Ray Johnson said in a statement. “However, once we learned of his involvement, we acted swiftly to minimize the possibility of any additional victims; and to hold Officer Cerna accountable for his actions.”

The video camera at the Mobil and Cerna’s website were removed during the department’s week-long investigation, police said. His record had been clear of any previous violations that would have raised suspicions.

Charges in St. Charles County stem from Cerna’s now-defunct website, police say. Cerna has admitted to the crimes and told investigators he placed ads on Craigslist posing as women wanting casual sex, and would send photos of a woman he didn’t know to men who responded.

After sending photos, Cerna provided a cellphone number and sent text messages from that number, giving his home address with instructions on what to do when men came to the front door.

Cerna said he would record video of men having anonymous oral sex with Cerna through a hole in a door. As many as 60 men visited his home over 18 months, Cerna told police.

At this time, two of those men, both 24, have been identified, police said.
