Dateline NBC “Secrets in Pleasant Prairie” April 19 2025 Recap & Preview

This Saturday, April 19, 2025, at 9/8c, Dateline NBC presents “Secrets in Pleasant Prairie”, a harrowing investigation into the death of Julie Jensen, whose death in December 1998 was initially believed to be a suicide but later turned out to be a chilling murder.

Julie Jensen’s husband, Mark Jensen, claimed that his wife had taken her own life after an apparent overdose, but her family never believed it. Just days before her death, Julie wrote a letter to law enforcement, expressing suspicion about her husband’s behavior and fearing for her life. The letter pointed directly to Mark, and this document would become a key piece of evidence in the years-long investigation into her death.

Dateline correspondent Andrea Canning covers the case, detailing how Julie’s family launched their own investigation after authorities initially ruled her death a suicide. Their persistence led to the discovery of new evidence, eventually resulting in Mark Jensen being charged with his wife’s murder.
