A Costa Mesa man was sentenced this week to three years in state prison for selling marijuana-laced brownies to students.
Isaac Greer, 33, pleaded guilty Monday to one count of furnishing marijuana to a minor and one count of sales of marijuana to a minor.
Police arrested Greer in March about a year after two incidents at Pomona Elementary School and TeWinkle Middle School in Costa Mesa sparked an investigation.
Students at the two schools brought brownies believed to contain pot and shared them with classmates, who became nauseous and told school officials.
Police were eventually led to Greer when parents of students at Newport Harbor High School reported a similar incident to police.
