Two Mountain Lake Park residents and two from Oakland have been charged with drug violations, stemming from separate drug investigations. Mountain Lake Park resident Bodine Jean Kelly and Matthew Norman Swapp were charged with possession of various drugs, including fentanyl, Alprazolam, and paraphernalia. Joshua Todd Culp and Krista Adair Ridder of Oakland were each charged with possession of heroin, meth, and paraphernalia. Those charges stem from a drug investigation that began in May, leading to the search of a residence in Oakland. A sawed-off shotgun was also recovered at a residence in Oakland.
