A Virginia man admitted Tuesday that he used an iPhone social networking application to lure a teenage girl to his home to have sex.

Virgil Moses Campbell pleaded guilty in U.S. District Court in Alexandria to transporting a minor across state lines to engage in sex.

Campbell, 44, is scheduled to be sentenced Oct. 22. He faces a mandatory minimum of 10 years in prison and could be sentenced to life in prison.

According to court documents, Campbell met a teenage girl using an application on his iPhone called "iDate Personals Dating Service for Singles of Any Sex" in January. The girl had listed herself as 18 years old, but was only 13.

The two first met in person in February, when they had sex at the girl's home in Upper Marlboro.

In April, when the girl was 14, Campbell arranged for her to come to his home in Alexandria, court documents show. A cab wouldn't take her because the driver didn't believe she could pay the fare.

The girl's mother saw the cab before it drove away, and the driver gave her Campbell's phone number, the documents said. The mother called Campbell and told him her daughter was only 14.

The next day, the girl successfully took a cab to Campbell's home and the two had sex. After a phone call from the girl's mother, the cab company called Fairfax County police to report suspicious activity.

Fairfax officers went to Campbell's home, where they found the girl under his bed. Campbell was arrested in May.

In exchange for the guilty plea, prosecutors dropped the two counts of traveling with intent to engage in illicit sexual conduct against Campbell.

William Watson, Campbell's attorney, did not return a call for comment on the plea.
