PEORIA (HOI) -- The Peoria County Sheriff's Office and coroner have identified the remains of a body found in the Illinois River more than three years ago.
Coroner Jamie Harwood identified the John Doe as John H. Frisch, who would have been 56 when his torso was found in Schuyler County in November 2016.
Harwood ruled the cause of death as blunt force head trauma.
"This was a horrific crime that occurred where John Frisch’s body was dismembered after his death and found in the Illinois River," said Peoria County Sheriff Brian Asbell in a press release Tuesday.
A skull found in June 2017 on the shore of the Illinois River in Kingston Mines has also been identified as Frisch's.
A Peoria County detective investigated and eliminated every reported missing person in the United States using identifiers and DNA from this John Doe. Detectives diligently worked with DNA Doe Project and they were able to give detectives a strong candidate through forensic genealogy, according to the release.
Harwood and his staff were able to confirm the John Doe’s identity by dental records from Hawaii, according to the release.
Frisch had never been reported missing, but used addresses in Peoria and Hawaii throughout his life.
