The Charles County Sheriff’s Office is working closely with the Department of Homeland Security Investigations and United States federal prosecutors in reference to the arrest of Alexander C. Sullivan, 37, a Charles County Sheriff’s Officer who was  charged on November 21 with possession of child pornography.

The  arrest is the result of an investigation that was initiated by Charles County Sheriff’s detectives who were alerted by the National Center for Missing and Exploited Children’s Internet Crimes Against Children program regarding someone uploading child pornography to a cell phone number based in Charles County.

Investigators assigned to the CCSO Criminal Investigations Division recognized the name of the person affiliated with the phone number as a fellow officer. Sheriff Troy D. Berry said detectives launched a swift and immediate investigation which was subsequently turned over to federal authorities at the recommendation of the Charles County State’s Attorney’s Office. “We will continue to work with our law enforcement partners as the investigation moves forward,” said Sheriff Berry.

In accordance with agency policy, Sullivan, a 10-year-veteran, has been suspended without pay pending the outcome of a criminal trial. Homeland Security Investigations is continuing the investigation.
