Santa Rosa police on Thursday arrested a man suspected of possessing heroin for sale.
Marco Antonio Jimenez-Menera, 19, is suspected of selling "red rock" heroin that is mixed with the synthetic opioid fentanyl, police said.
He is believed to be part of a drug trafficking organization that distributes the drug throughout Santa Rosa and surrounding Sonoma County areas, police said.
Police began investigating a possible drug trafficking organization in December.
When Jimenez-Menera was arrested at his residence at 3900 Montgomery Drive, detectives found two pounds of suspected red rock heroin on his person and $2,000 in cash, packaging material, digital scales and cell phones in his apartment, police said.
Jimenez-Menera was booked in the Sonoma County Jail for possession for sale of heroin.
