The unidentified boy brought the ounce of drugs, worth roughly $3,700, to the Sweet Springs Elementary School on Sept. 6, according to local KCTV-5.

The students had been asked to bring “pictures of their family for show and tell,” court documents said.

Shocked school officials called the police about 8:30 a.m., and officers executing a search warrant found a crack pipe at the boy’s home. His mother, 32-year-old Michelle Marie Cheatham, was charged with possession of a controlled substance and one count of first-degree child endangerment.

The rocks brought in by the boy tested positive for methamphetamine.

Police Chief Richard Downing told KCTV-5 that the incident marked a first in his law enforcement career.

“When I called the prosecutor about it, they said, ‘You’re kidding me, aren’t you?” Downing said.

After posting $7,500 bail, Cheatham was hospitalized with complications from a previous gastrointestinal surgery, a friend told KCTV-5.
