The Lancaster County Human Trafficking Task Force, working on a tip from the Federal Bureau of Investigation unit, arrested a Lititz sex offender on May 3, 2022.

Sean Deemer, 54 of the 500 block of Golden Street, stands charged with 13 crimes on two dockets after the FBI referred its undercover investigation to the Lancaster County Human Trafficking Task Force.

The charges on the first docket include three different types of unlawful contact with a minor, disseminating explicit sexual material to a minor, criminal solicitation, and criminal use of a communication facility.

The charges on the second docket include involuntary deviate sexual intercourse with a child, three different types of unlawful contact with a minor, photographing or filming a sex act of a child, criminal use of a communication facility, corruption of minors, and disseminating explicit sexual material to a minor.

All these charges are felonies and charged as attempted or solicited acts since Deemer was speaking to an undercover officer, not a child.

Between the dates of May 6 and 12, 2021, an undercover agent with the FBI posed as an 11-year-old girl on the mobile messaging application, KiK, and had a conversation with the defendant.

A subpoena served on KiK by the FBI revealed the IP addresses used during the conversation, which tracked back to the defendant.

During the conversation between the undercover agent and defendant, 147 messages were sent and 142 occurred after the undercover identified as an 11-year-old girl.

Multiple explicit and lewd messages and photos were sent and requested by the defendant.

The case was then brought to the attention of the Lancaster County Human Trafficking Task Force on April 27, 2022.

The HTTF then began an undercover conversation with the defendant posing as a 12-year-old girl. The defendant again sent and made multiple requests of the minor to send explicit and lewd messages and photos.

Deemer was arraigned on $350,000 bail and is currently in Lancaster County Prison. His preliminary hearing is scheduled for May 12 at Magisterial District Judge Edward Tobin’s office.

Deemer is presumed innocent until proven guilty.

Lititz Borough Police and Human Trafficking Task Force Detective P.J. Savage filed charges on the first docket; Lancaster City Bureau of Police and Human Trafficking Task Force Detective Jessica Higgins filed charges on the second docket.

Assistant District Attorney Fritz Haverstick approved charges.
