Matthew McMullen, former Pentagon police officer, sentenced for child sex offense

A former police officer for the Department of Defense was sentenced Tuesday for traveling interstate to engage in illicit sexual conduct and enticing a minor, the U.S. Attorney Ronald C. Machen Jr. announced.

Matthew McMullen, 27, was sentenced to 57 months in prison. McMullen, of California, Md., pled guilty to the charges in April 2011 in the District Court for the District of Columbia.

McMullen contacted an undercover officer on a social networking site in February, according to the government’s evidence. At the time, he was working for the Department of Defense as a police officer.

McMullen began emailing the undercover officer and expressed interest in having sexual contact with an under-aged child. The defendant traveled from Maryland to a pre-arranged meeting place in Washington, D.C. When he arrived, he was arrested.

After his prison term, McMullen will be placed on 10 years of supervised release.
