(YOUNGSTOWN, Ohio) — Ohio Attorney General Dave Yost today announced that a Mahoning County man, Andrew Herrmann, has been sentenced to 12 years in prison for his role in the murder and dismemberment of Shannon Graves.
“This prison sentence is the final chapter of one of the most brutal cases in memory,” Yost said. “Special Prosecutor Dan Kasaris did a masterful job in these cases to deliver justice and closure for the victim’s family.”
Herrmann pleaded guilty to four counts of tampering with evidence (F3) and one count each of abuse of a corpse (F5) and engaging in a pattern of corrupt activity (F1).
This is the fourth conviction related to the murder of Graves. Arturo Novoa, aka Anthony Gonzalez, pleaded guilty in May 2019 to the murder and cover-up. He was sentenced to 48 years to life in prison. Katrina Layton was sentenced on Jan. 29 to 18 years in prison for her role in the case. Michelle Ihlenfeld, Herrmann’s wife, received a sentence of two years in prison, six months in a halfway house and five years of community controlled for her actions in the case.
The Youngstown Police Department, Mahoning County Sheriff’s Office and the FBI investigated the case. The Special Prosecutions Section of the Ohio Attorney General’s Office prosecuted the case.
