Mom took his brownies to serve at her card game. Then the 911 calls started.

The 46-year-old man reportedly told police he wasn't aware his mother had taken the brownies to the senior center.

A South Dakota music teacher was arrested after his mother served his cannabis brownies at her card game, resulting in multiple 911 calls.

The 46-year-old man reportedly told police he wasn’t aware his mother had taken the brownies to a gathering Jan. 4 at the senior center in Tabor, a town of 400 people near Yankton.

Later that evening, dispatchers received 911 calls reporting possible poisonings. They found that all the patients had been at the card game and had eaten the brownies.

The following morning, police contacted the woman who had brought the brownies. She gave them the leftovers and said they had been baked by her son.

Police then went to the town’s elementary school, where the son works. He told them he had made the brownies with THC butter he had brought back from a visit to Colorado. He said he was asleep when his mother left for the card game.

The man was charged with one count of possession of a controlled substance, a Class 5 felony. If convicted, he could face up to five years in prison and a $10,000 fine. He’s due in court on Jan. 25.

Police seized a half-pound of the THC butter that remained.
