An Upper Arlington police lieutenant who was charged in January with soliciting an undercover officer for sex has retired from the department as part of a guilty plea in the case.

Jeff Conrad, 48, pleaded guilty April 2 to a count of loitering to engage in solicitation, reduced from a more-serious misdemeanor charge of solicitation.

Franklin County Municipal Judge Amy Salerno imposed a $350 fine and court costs, as recommended by prosecuting and defense attorneys as part of the plea agreement.

The retirement for Conrad, who has been on paid administrative leave since his arrest, becomes effective Friday, said Emma Speight, a spokeswoman for Upper Arlington. His departure from the department will bring an end to an internal investigation of the incident, she said.

According to an affidavit filed by the Columbus police vice unit, the arrest occurred Jan. 10 at the Varsity Inn in the 1400 block of Olentangy River Road in northwest Columbus.

Conrad had answered an ad under the dating section on Backpage.com and called and texted a female Columbus police detective who was posing as a prostitute. They agreed to meet at the Varsity Inn, where Conrad would pay $40 for intercourse and oral sex, court records state.

Conrad was arrested after he met the woman in a motel room, placed the money on a table and discussed whether a condom would be used, police said.

Defense attorney Mark C. Collins said his client has already attended "John school," an educational program for men convicted of solicitation offenses.

Conrad has been with the Upper Arlington police force for more than 22 years and was one of three lieutenants, ranked just below the chief.
