SOMERVILLE, N.J. — A woman is accused of using children’s drawings to smuggle prescription drugs to her boyfriend in a New Jersey jail.

Somerset County Sheriff Frank Provenzano says staff noticed something strange about mail addressed to inmate Michael Gill on June 15. A K-9 unit was called and alerted on what turned out to be the opioid Suboxone concealed in the drawings, authorities say. The sheriff says another letter with children’s drawings addressed to Gill arrived June 20 with more Suboxone in it. Authorities charged 37-year-old Casey Giles, of Bridgewater, with possession with intent to distribute a controlled dangerous substance. She was jailed on $20,000 bail. Gill, of Oxford, was charged with attempting to possess a controlled dangerous substance, and his bail was set at $10,000.
