Summary based on the NamUs case record (MP153048) and 4 other sources
In the small community of Wagoner, Oklahoma, a sense of unease settled when 17-year-old Catlin Nichole Sivak was reported missing. She was last seen on November 20, 2025, a date that would become etched in the memory of her loved ones and the community. At the time of her disappearance, Catlin, a young woman with brown hair highlighted with blonde streaks and blue eyes, was described as being 5 feet tall and weighing around 120 pounds. She wore eyeglasses with clear frames and dark-colored arms. The last image of her, captured by a recent body camera, shows a glimpse of the young woman whose absence would soon be deeply felt. When she was last seen, Catlin was dressed comfortably in pajama pants, a top of an unknown color, and tan Birkenstocks. Her disappearance initiated an investigation led by the Wagoner County Sheriff's Office, as her family and friends began a difficult and uncertain wait for answers.

The circumstances surrounding Catlin's disappearance are shrouded in mystery, with few details available to the public. The official report notes that she went missing from and has a primary residence on tribal land, adding a layer of complexity to the investigation. The case was officially created on December 4, 2025, and last modified on December 23, 2025. Beyond the description of her last known attire, no further information regarding her direction of travel or potential destination has been released. The lack of information about her means of transport or whether she had any personal documents with her has left investigators with a challenging puzzle to piece together. The case is being handled by Deputy Whalen Phipps of the Wagoner County Sheriff's Office, under the agency case number 25-1265.

The official record of Catlin's disappearance is cataloged under the NamUs case number MP153048, a stark reminder of her ongoing absence. The community is left to grapple with the limited information available, hoping for a breakthrough that will bring Catlin home safely. The investigation remains active, with law enforcement continuing their efforts to uncover any leads that might shed light on her whereabouts. The overview of the case is one of a sudden and unexplained disappearance, leaving a family in distress and a community on alert. The absence of any distinctive physical features reported, aside from her glasses, makes public appeals for information all the more crucial in the search for the missing teenager.
