MONTGOMERY COUNTY, N.C. (WGHP) — A man faces multiple charges after four inmates overdosed Thursday in the Montgomery County Detention Center, according to a news release from the sheriff’s office.

Detention officers provided lifesaving measures before the inmates were taken to the hospitals.

Deputies think that three of the inmates used drugs that tested positive for fentanyl while the fourth person reportedly overdosed after being contaminated while doing CPR. Two of the four inmates have been released from the hospital.

Investigators determined that Jiovanny Munoz, 23, of Biscoe, brought the drugs into the jail on Wednesday when he was arrested on outstanding warrants. He also was charged with felony possession of a controlled substance.

Munoz was strip-searched when he was booked, per jail policy, and deputies said he had the drugs inside a body cavity. He was charged with possession with intent to sell and deliver drugs and possession of a controlled substance inside of a confinement facility.

He was placed under a $250,000 bond.

Investigators are still working to determine whether anyone helped Munoz get the drugs inside the jail.
