Jonathon Minard, 14, the missing Carroll County teen who was found in a shallow grave on April 19, died from “acute fentanyl intoxication,” and his death has been ruled a homicide, according to the Carroll County Sheriff’s Office.

“Homicide, in death investigation and forensic medicine, simply means that the death was caused by the actions or omissions of another person. Some of these deaths may be subject to criminal prosecution, others are not,” said Carroll County Coroner Dr. Mandal Haas.

Jonathan’s body was found on a Washington Township farm a few days after he was reported missing on April 13, approximately 7 miles from his last known location in Carroll County, Ohio.

The situation began when investigators say Jonathan complained of a toothache and was going to call his mother to go home, but the sheriff’s office said his mother never received that call.

There was a 29-year-old man last seen with Jonathan, initially identified as a person of interest being questioned in the case, but no additional information has been released about it since.

In reference to the case, Sheriff Dale Williams said, “This takes time and we want to be thorough. I also want the public to know that they are safe. There is no suggestion that the public is in danger or that there are any ongoing threats to public safety.”

Carroll County Prosecutor Steven Barnett said that the criminal investigation is still ongoing. Steven Barnett would not answer questions about how the boy got the fentanyl or if someone buried him after an overdose.

“We will take appropriate legal action when we are comfortable that the investigation is sufficiently complete to do so,” Carroll County Prosecuting Attorney Steven Barnett said.
