Sheriff's deputies arrested 19 "former and present" Monte Vista High School students Thursday morning, capping a six-month investigation into narcotics trafficking on and around campus.
Sheriff's Department spokesman Sgt. Rich Hendrickson said an undercover deputy posing as a student made 26 small purchases of methamphetamines and marijuana since September. He added that 17 of the drug transactions occurred on the Spring Valley school's grounds, and the others took place near the high school after negotiations were made at the campus.
On Wednesday, deputies said they believe they may have cracked two alleged drug suppliers for the students when they executed a search warrant on a Spring Valley home in the 4000 block of North Bonita Street.
Arrested and booked in connection with possession of methamphetamines were Gary Martin Sullivan, 26, and Ann Marie Sullivan, 25. An arrest warrant for another student, who moved out of California, is still outstanding, the Sheriff's Department said.
