Three people wanted in connection with a heroin investigation are behind bars in Lawrence County, Ohio.

The Lawrence County Prosecutor’s Office says around 6 a.m Tuesday, officers with the Lawrence Drug and Major Crimes Task Force and the Lawrence County Sheriff’s Office made a traffic stop.

Investigators say James Martin, II, 39, Stephanie Martin, 42, and Keith Cremeans, 37, all of Chesapeake, Ohio were in the car.

The Prosecutor’s Office says warrants for trafficking heroin were issued for all three on February 2, following a controlled buy of heroin.

All three were taken into custody and a search warrant was executed at James and Stephanie Martin’s apartment on Township Road 1039 in Chesapeake.

Investigators say they found heroin, marijuana, cash, and a loaded gun in the apartment.

The Prosecutor’s Office also says a 7-year-old child was in the home at the time of the search.

All three will be charged with three new counts of trafficking drug, including trafficking in heroin in excess of 10 grams in the presence of a juvenile, which carries a possible 11-year prison sentence and $20,000 fine.

All three are expected to be in court later this week.

More arrests are expected to be made.
