Summary based on the NamUs case record (MP145935)
Jennifer Marie Gilleland was a female, 29 years old when she was last seen in Everett, Washington, on March 10, 2016. Her last known contact was recorded in Snohomish County, in the Everett area, at 3:23 p.m., and the silence that followed became the central fact around which her missing person case has remained built. Jennifer was known as a White/Caucasian woman with brown hair and green eyes, about 5 feet 3 inches tall and approximately 110 pounds.
In the official case information, she is connected not only to Everett but also to Monroe, Washington, where she had lived after moving west from Ohio and Oregon. Her case is now documented through NamUs, a federal missing-persons resource that supports long-term missing, unidentified, and unclaimed person cases across the country.
Jennifer’s life before she disappeared had taken her across several states. She was originally from Ohio and moved to Oregon in 2009 to live with her mother. Around 2012, mother and daughter relocated again, this time to Monroe, Washington, in Snohomish County. In late 2014, her mother moved to Wyoming, while Jennifer stayed behind in Washington. The last time her family heard from her was by phone in mid-March 2015, about a year before the final known contact documented in Snohomish County. That gap is part of what makes the case especially painful: Jennifer’s loved ones had already been separated from her by distance and limited contact, and then the last confirmed trace of her simply ended.
The official circumstances describe a woman who seemingly vanished from ordinary life without a clear public explanation. After March 10, 2016, there were no further known contacts with Jennifer, and no known social media posts from her or from anyone reporting that they had seen or heard from her. Publicly available details do not identify a vehicle, clothing, travel plan, destination, or confirmed person she was last with. The absence of those details leaves investigators and family with a narrow factual timeline: Jennifer had remained in Snohomish County after her mother left Washington; family contact had stopped; then, on March 10, 2016, the last known contact occurred in the Everett area. After that, the record goes quiet.
The Monroe Police Department is listed as the investigating agency for Jennifer’s case, with Detective Paul Henderson associated with the investigation and agency case number 2025-6245. The agency date reported is listed as April 16, 2025, which indicates that although Jennifer’s last known contact was in 2016, the formal public case record reflects later law enforcement reporting activity. Washington’s statewide missing-persons framework also relies on local law enforcement reporting before broader state resources can become involved; WASPC explains that Washington’s missing-persons website is maintained for public information, receives data from the Washington State Patrol, and directs people to report missing persons through local law enforcement.
The available case details also show that Jennifer was not listed as missing from tribal land, found on tribal land, or primarily residing on tribal land. DNA family reference information is noted as collected from a daughter, a detail that quietly underscores the human cost of the case: Jennifer was not only a name in a database but someone’s child, someone’s family member, and someone whose absence continued long enough that relatives and investigators had to preserve identifying information for comparison and future answers. NamUs notes that its services can include analytical support, indications-of-life research, family contact information for case inquiries, DNA collection, and coordination among agencies in long-term cases.
As of the available public information, Jennifer Marie Gilleland’s case is best understood as a long-term missing person case rooted in Snohomish County, Washington, with the last known contact on March 10, 2016, in Everett. The story begins with Jennifer’s moves from Ohio to Oregon and then to Monroe, continues through her separation from close family after her mother relocated to Wyoming, and narrows into a troubling final point of contact in Everett with no public trail afterward. The case remains defined by limited confirmed facts, a long lapse in contact, and the hope that someone may still know something that can help explain what happened. Washington State Patrol’s Missing and Unidentified Persons Unit provides a 24-hour tip and assistance line for missing-person matters, and state guidance emphasizes that local law enforcement must be notified before MUPU can become involved. Jennifer’s case is a quiet, unresolved disappearance: a woman from Ohio who built a life in the Pacific Northwest, last known to be in Everett in March 2016, and whose family and investigators still need the missing pieces that could finally bring clarity.Last Seen: Mar 10, 2016
