The Humboldt County jail will only accept incoming mail on plain or lined white paper starting February 1, after Correctional officers noticed a rise in attempts to sneak drugs into the jail through colored letters.

Humboldt County Sheriff’s Office Public Information Officer Samantha Karges told the Outpost via email that white paper makes contraband detection easier.

“We’ve been seeing an increase in attempts to send narcotics into the jail by soaking/contaminating the paper,” Karges said. “White paper makes it easier for our deputies to detect if the paper has been contaminated with narcotics.”

The Humboldt County Correctional Facility is changing its policy on inmate mail in an effort to increase safety and security by deterring the introduction of contraband in the facility.

Beginning Feb. 1, 2018, the Correctional Facility will only be accepting incoming mail that is written on plain/lined white paper or postcards. The facility will no longer be accepting greeting cards, letters on colored paper, or letters on cardstock paper.

Any mail received that is not on white plain/lined paper will be returned to the sender with a notification for the return. Inmates may still continue to receive pictures that are no larger than 5”X7”.
