JNET: Second Man Found Guilty in 2020 Overdose Death of Mossyrock Woman


A second person has been convicted in the 2020 overdose death of a Mossyrock woman, according to a news release from the Joint Narcotic Enforcement Team (JNET) on Thursday. 

Layla R. Horton, 27, was discovered dead in her Mossyrock home after overdosing on fentanyl on Nov. 10, 2020. 

Joshua Jacobs, then 35, of Mossyrock, was arrested in January 2021 after investigators learned he sold five fentanyl pills to Horton. Jacobs had sent a text message to Horton the day before her death advising her to try one half of a dose first and telling her to be careful, according to court documents. Horton replied that she had taken a whole dose. She did not reply to Horton’s next text message wishing her a “good, safe rest of the night.” She was found dead shortly thereafter.

Jacobs was sentenced to two and a half years in prison after pleading guilty to one count of controlled substance homicide in January 2022.

“With the growing deadly fentanyl epidemic in mind, JNET detectives shifted their investigation to identify the source who was supplying Jacobs and potentially other local drug dealers with the fentanyl killing the community,” JNET stated in the news release.

On Wednesday, JNET announced that its investigation led to another arrest and subsequent conviction in Lewis County Superior Court this week. Jason Jensen, 30, of University Place, was arrested Jan. 11, 2021. A search of his vehicle revealed fentanyl-laced pills, heroin and methamphetamine, according to JNET. 

On Wednesday, Oct. 19, Jensen was found guilty of unlawful delivery of a controlled substance. fentanyl, and unlawful possession of a controlled substance with intent to deliver after a two-day trial, according to JNET. 

Sentencing is scheduled for Nov. 8 and Jensen is facing up to 15 years in prison. 

JNET includes members of the Centralia Police Department, the Chehalis Police Department, the Washington Department of Corrections and the Drug Enforcement Administration. 

“JNET will continue to vigorously investigate crimes related to fentanyl overdoses and sales,” JNET stated in the release.
