A diligent principal and a perceptive teacher helped police make the first arrest under the new Jessica Lunsford Act in Mecklenburg County.
The arrest may also be the first of its kind in the state.
According to Charlotte-Mecklenburg Schools Law Enforcement, 30-year-old Douglas Dellinger, a registered sex offender, recently moved to Huntersville. When he registered his new address, nearby schools, including Bradley Middle and Barnette Elementary, were notified.
Pictures of Dellinger were handed out and a teacher at Barnette Elementary recognized the photo.
"The teacher said, 'I know that guy and I think he's been in my classroom.’ As soon as (the administration) found that out, they called us," said Bud Cesena, director of CMS Law Enforcement.
Detectives immediately started looking into the claims. That teacher told the principal that Dellinger had been bringing a young girl to school in the past few weeks.
Police believe Dellinger had been walking his girlfriend’s daughter to class in the morning.
Under the Jessica Lunsford Act, which was enacted in North Carolina in December, it's now a felony for certain sex offenders to step foot on any school property.
According to court records, Dellinger was convicted of indecent liberties with a minor in 2004, which qualifies him for the Lunsford Act.
Detectives went to Dellinger's Huntersville residence Wednesday afternoon, but he wasn't there.
He was arrested in uptown Charlotte while trying to register a new address.
