The San Luis Obispo County Criminal Grand Jury issued indictments this week against 13 people accused of drug trafficking.
According to the District Attorney's Office, the drug trafficking operation was based in Paso Robles and operated in multiple locations throughout San Luis Obispo County, including a home on Veronica Dr. next to Paso Robles High School.
The defendants face charges alleging that they conspired to sell and transport heroin and methamphetamine.
Authorities say Rogelio Miranda, 42, was the leader of the group. They say he sourced the drugs from Mexico.
The indictments were issued Monday after a six-day Criminal Grand Jury Hearing.
On Friday, eleven of the defendants appeared in court for arraignment. One has posted bail and one has not yet been arrested. A felony arrest warrant has been issued for Samantha Hogle, 53, of Paso Robles.
The DA's Office says the grand jury hearing and indictments were the results of a year-long investigation by the San Luis Obispo County Sheriff's Office.
The defendants are due back in court on Monday.
