ROSEVILLE (CBS13) — A Roseville man has been charged with homicide after someone overdosed and died from fentanyl-laced drugs he allegedly sold them.

Roseville police say 20-year-old Carson Schewe was arrested last week after an extensive investigation into a drug operation he was allegedly running. Detectives seized $100,000 in cash and an unregistered “ghost gun.” Further, police say pills suspected to be laced with fentanyl were found.
