MARION COUNTY — A 40-year-old Centralia woman charged with felony Drug-Induced Homicide pleaded guilty Tuesday in Marion County Court to a lesser charge in exchange for her truthful testimony regarding a man charged in an unrelated murder case.

Jeri L. Carpenter was sentenced to four years probation after she pleaded guilty to Class 2 felony possession with the intent to deliver a narcotic.

Carpenter was also ordered to serve 183 days in jail with credit for 183 days served and to testify truthfully in a hearing regarding Mantez Duncan.

The 24-year-old Duncan is charged with first-degree murder in the December 2019 shooting death of 39-year-old Clendar Edmond.

Carpenter was charged in January 2020 with the September 2019 overdose death of 36-year-old Mathew E. Proksha.

According to Centralia Police Chief Greg Dodson, officers arrested Carpenter after she was identified as being responsible for providing Proksha with the drugs that resulted in his death. Toxicology results indicated that Proksha died of a Fentanyl overdose.

Dodson says Fentanyl is commonly mixed with or substituted for heroin and is typically much more potent and has a higher risk of overdose.
