Jason Mendez-Ramos, 36, was found dead in a wooded area on the University of Wisconsin–Green Bay campus on September 28, 2021. Investigators determined his death did not occur at that location and concluded he was the victim of a homicide; detectives asked the public for help locating his red 2010 Ford Fusion to trace his final movements.

Police say evidence linked the killing to a dispute over money allegedly owed to Pedro Santiago-Marquez. Authorities allege Santiago-Marquez either shot Mendez-Ramos on September 27, 2021, or ordered the shooting, then directed that the body be taken to the university arboretum and set on fire. Security footage, cellphone tracking data, and DNA evidence tied an associate, Jeisaac Rodriguez-Garcia, to the scene where the body was burned. Two other men connected to Santiago-Marquez’s business, Jeisaac Rodriguez-Garcia and Alexander Burgos-Mojica, were also implicated for assisting in disposing of evidence.

Anyone who knew Mendez-Ramos, saw a red 2010 Ford Fusion in the Green Bay area around September 27–28, 2021, or has information about the killing is asked to come forward.
