A Kansas City man who used to teach middle school students has admitted to preying on a 12-year-old girl online.
Robert Dobbertin, 40, pleaded guilty Monday to a federal charge of enticement of a minor.
A plea agreement filed in federal court indicates he met the child on Teenspot.com.
A review of the site on the parental monitoring site called Common Sense Media indicates members are supposed to be older than 13 and younger than 23, but the facts agreed in the plea make it clear that those age limits can be skirted.
The site includes chat rooms with titles like "singles" and "hottub" and contains a section where members can rate each other's popularity and appearance.
In 2009, investigators seized computers from Dobbertin's home in the 6100 block of Longwood Ave., in Kansas City, KS. He has since moved to Kansas City, MO.
As part of his plea, Dobbertin admitted that the girl was 12 years old when he began his sexually explicit online relationship with her in 2008.
Dobbertin said she lived in Orange County, CA, and her mother uncovered their relationship six months later, after it had progressed to phone calls and swapping of explicit photos and videos.
Dobbertin told the girl he planned to visit her in California to have sex with her. He even used his real name and age.
The girl told investigators she "knew [him] as Robert Dobbertin, age 36, who worked at a college, was married and had a 4-year-old daughter."
His online resume indicates he worked at Donnelly College teaching math.
Before that, he taught seventh-grade social studies at KCK's Northwest Middle School during the 2005-2006 school year.
The district spokesman was not aware of any suspect behavior during Dobbertin's tenure, which ended two years prior to the cross-state crime.
Court records show Dobbertin and his wife divorced in 2010.
In exchange for his guilty plea, the U.S. attorney dropped a second count of aggravated indecent liberties with a child and asked that Dobbertin get the minimum sentence of 10 years in prison.
A judge will get the final call on his sentence. His sentencing is set for July 22.
