Two Treasure Valley men are charged with trafficking in heroin after deputies found them then in possession of about 287 grams of the drug on Monday.
Adam Paul Esposito and Alejandro Valadez Mariscal are both being held in the Ada County Jail on $500,000 bonds. Preliminary hearings for both men will be set for early September.
Detectives began their investigation earlier this summer.
Deputies seized 100 grams of heroin and arrested the 28-year-old Esposito near a Boise-area hotel Monday afternoon.
They arrested 28-year-old Valadez Mariscal at Nampa home a short time later. Deputies later seized an additional 187 grams of heroin and a small amount of methamphetamine from a Boise-area hotel room Valadez Mariscal was staying at.
The crime of trafficking in heroin is punishable by up to life in prison.
