Corrections Officer Glen Mead and his canine partner, Karma, were conducting a routine search of incoming inmate mail on Friday when Karma alerted on a particular piece of correspondence, according to a news release from Lorain County Sheriff Phil Stammitti.
The letter was isolated and checked further, where it was determined to contain marijuana, the release said.
The incident remains under investigation.
This is the second incident involving drugs at the jail in recent weeks.
On Dec. 24, deputies and a drug-sniffing dog found 14 grams of cocaine hidden in an inmate’s pants inside the medium-security men’s housing area of the jail.
The inmate, Obed Sanchez, may be charged with possession of drugs and trafficking in drugs, but the charges will be determined by a county grand jury.
