Five-Year Anniversary of the Disappearance of Melissa A. Trumpy
Carroll County, Illinois – Today marks the five-year anniversary of the disappearance of Melissa A. Trumpy. The Carroll County Sheriff’s Office remains fully committed to finding answers and bringing a resolution to Melissa’s family and friends. This case has not been forgotten, and investigators continue to actively pursue all leads related to her disappearance.
The investigation into the disappearance of Melissa A. Trumpy began on October 27, 2021, after her boyfriend, Derek S. Hammer (DOB 10/29/1986), was taken into custody by Carroll County law enforcement on outstanding warrants from Green County, Wisconsin. Melissa resided in Monticello, Wisconsin, and was believed to have been in Shannon, Illinois, around the time she went missing. Her vehicle was later located on Bolton Road in Stephenson County.
Over the past five years, this case has remained an active and ongoing investigation. The Carroll County Sheriff’s Office continues to work with numerous local, state, and federal partners, including the Illinois State Police, Federal Bureau of Investigation, Federal Fish and Wildlife Police, Illinois Department of Natural Resources, Stephenson County Sheriff’s Office, Green County (WI) Sheriff’s Office, Wisconsin Department of Criminal Investigations, Ogle County Sheriff’s Office, Orange County (FL) Sheriff’s Office, Tennessee State Police, Northwest Illinois Critical Incident Response Team, Illinois Appellate Prosecutor’s Office, Carroll County State’s Attorney, Illinois Attorney General’s Office, Jacksonville Police Department, and many volunteer search and rescue groups.
The Illinois Attorney General’s Office continues to play an active role in this investigation. Both its attorneys and investigators remain directly involved, continuing their efforts alongside the Carroll County Sheriff’s Office as we work together to find answers regarding Melissa’s disappearance.
Together, these teams continue to follow up on every lead received, re-examine each step of the case, continue with new search warrants and investigative actions as well as utilizing new technology.
We remain deeply sympathetic to Melissa’s family and friends, who have endured five long years without answers. We recognize the heartache and uncertainty they continue to face, particularly as another anniversary passes. Melissa has not been
