For three months, a Cobb County college student communicated with a 13-year-old girl he met online, according to police.

Then on May 2, Joshua Measroch allegedly took the relationship further. The 21-year-old allegedly drove 50 miles from his east Cobb home to pick up the girl at her Newton County home, according to an arrest warrant obtained by The Atlanta Journal-Constitution.

Measroch then took the girl back to Cobb County, where he kept her for more than a month in a room, police said.

The girl was initially believed to be a runaway because many of her personal items were missing from her Covington home, police previously said. Police also said the girl was a frequent user of social media sites at the time of her disappearance.

Measroch was arrested Friday and booked into the Cobb County jail, where he was being held Monday night without bond, booking records show.

He was charged with enticing a child for indecent purpose and interference with custody, among other felony an misdemeanor charges.

Newton officials say the child’s parents were instrumental in locating her.
