Arrest warrants were issued for two suspects allegedly involved in a drug-induced homicide that occurred in February.

Grant A. Kersten, 28, and Cornelius A. Jones, 36, both of DeKalb, are being held at the DeKalb County Jail on unrelated drug charges, according to a DeKalb Police press release.

The investigation began on Feb. 27 when officers responded to a residence in the 700 block of North Sixth Street for a person not breathing, according to the release. The victim was determined to have died at the scene.

The release stated evidence from the scene along with autopsy results that indicated the victim died from an overdose of heroin.

Police determined that Kersten delivered the heroin to the victim within hours prior to his death, according to the release.

The heroin Kersten allegedly delivered to the victim was found to be previously purchased from Jones, the release stated.

“A lot of hours were spent with surveillance and interviews, connecting other cases to [the incident],” said DeKalb Police Lt. Gary Spangler.

Through those methods, as well as talking to known drug users, Spangler said witnesses and information were able to be found.
