Wauconda man held on drug-induced homicide charge after Cary drug sale turned fatal, authorities say

David W. Johnson, 70, of Wauconda, has been charged with drug-induced homicide and delivery of cocaine following the death of a 68-year-old man in December 2025. Prosecutors allege Johnson sold the drugs at a park in Cary. A judge denied Johnson’s pretrial release, citing his status as a continuing threat to the community. Johnson was also found in possession of cocaine and multiple cellphones at the time of his arrest.
