Londonderry Budget Committee Member Arrested On 15 Felony Child Sexual Abuse Image Charges

LONDONDERRY, NH — A Londonderry budget committee member from an active political family in town was arrested on Thursday on 15 felony counts of possessing child sexual abuse images.

Timothy Siekmann, 60, of Hovey Road in Londonderry, was arrested on a warrant at 9:54 a.m. on Thursday.

The case against Siekmann started in early August 2022 after a detective with the Derry Police Department received a cyber tip from the Internet Crimes Against Children Task Force about three files uploaded via a Microsoft Bing Image peer-to-peer client server around 3:45 a.m. on June 3, 2022. The internet protocol address for the service provider was Consolidated Communications in Derry. The files, an affidavit said, were locked and required a search warrant.

The detective filed a request for a search warrant, and it was approved, confirming the photos were child pornography, a report said.

Another search warrant was requested of the service provider, which a judge also approved. The affidavit said it led to an account belonging to Siekmann on Hovey Road in Londonderry. The Derry detective reassigned the investigation to the Londonderry police for follow-up, the report stated.

A Londonderry detective requested a search warrant of Siekmann’s home on March 9. The Derry detective was also at the house, the report said. During an interview, the detective wrote in an affidavit, “Siekmann did not admit to possessing child sexual abuse material.” The report said he confirmed he had a work computer and cellphone in a den at the home.

The detective said the work laptop had a solid-state drive attached to it, and he ran a disk image duplication of the hard drive. The detective said after searching, he found “numerous child sexual abuse material in a downloads folder,” according to the affidavit. The report said the images involved girls from 2 to 9 years of age.

A warrant was issued for Siekmann’s arrest on July 7, and he was arrested at home on Thursday. He faces up to 20 years in jail.

Siekmann is an elected Londonderry budget committee member. His term expires in March 2024. As of Friday, he was still listed as a committee member on the town’s website.

Londonderry’s town manager, Michael Malaguti, said Siekmann had not resigned from the committee.

According to superior court records, Siekmann was sued by American Express in July 2021 due to nearly $4,900 in unpaid credit card bills. He then sued his wife, Tammy Marie Siekman, in late August 2021, “requesting relief to make payment arrangements to pay Amex.” The case was dismissed in September 2021 due to “failure to pay required filing fee.”

In December 2021, a judgment was rendered on behalf of the bank against Timothy Siekmann for the payments to Amex.

Tammy Marie Siekman is the former chairwoman of the Londonderry Democrat Town Committee and an unsuccessful candidate for town council earlier this year, placing fifth. She also ran unsuccessfully as a Democrat candidate for state representative in 2014 and 2022 and unsuccessfully for state Senate in 2010, 2016, and 2018.

In a statement, Public Information Officer Sgt. Chris Olson said residents can anonymously report crime tips by visiting the department's website at londonderrynhpd.gov or calling the department’s tip line at 603-425-5999.
