Derrick M. Guilder

Derrick M. Guilder sits in Washington County Court on Friday during sentencing for his murder/arsonist case.

A Washington County murder case will be the subject of an episode on a show on the Investigation Discovery channel next week.

The network's "Body Cam" show will feature the investigation of the September 2017 killing of 18-year-old Ashley Coltrain by her then-boyfriend Derrick M. Guilder. Guilder, upset that their relationship was ending, set their Hudson Falls home on fire, then escaped and left Coltrain to die in a smoke-filled bedroom.

Guilder pleaded guilty to second-degree murder, and was sentenced to 22-years-to-life in state prison.

Guilder was arrested after he confessed to setting the fire, a confession from his hospital bed that police surreptitiously videotaped, linked here.

Hudson Falls Police Chief Scott Gillis, who was then a detective and the lead investigator in the case, said the Discovery network sent personnel to Hudson Falls to interview numerous Hudson Falls and Washington County sheriff's officers. Gillis and Hudson Falls Police Officer Ed Ackley were among those featured.

State Police were also actively involved in the investigation, the agency had no interest in its officers being involved in the TV show.

The show is scheduled to air at 10 p.m. Dec. 11 on Spectrum Cable Channel 138.
