MOORESVILLE, N.C. -- Investigators from the Iredell County Sheriff's Office have made four arrests in connection with a suspected drug ring centered around Lake Norman High School.
Investigators provided pictures of heroin and LSD that had been purchased by undercover officers during a two month long investigation.
They say they also found marijuana and an illegal bath salt sold as a "Molly" by the suspects.
The four people arrested are being called key distributors of illegal narcotics to numerous high school students.
Elliott Siegler, a former student, faces charges including trafficking in heroin and opium.
His mother, Denise Mingle was also charged with using their home for drug deals.
"This happened at different locations and one of the places the undercover officer was at was her residence during an actual narcotics purchase," said Major Darren Campbell of the Sheriff's Office.
Windows at that house were shuttered and there was no answer Tuesday night when NBC Charlotte reporter Rad Berky stopped by to try to ask some questions.
The other two people arrested are Daniel Gilbert Brown and Thomas Jordan Wykoff, both former Lake Norman students and now both are facing serious drug charges.
As he was leaving the school, student Damon Reddy said, "people are being taken out of classes and searched."
Investigators say a juvenile who's name is not being made public was the main supplier of LSD at the school.
"We know that drugs were being bought and sold at the school," said Maj. Campbell.
Campbell said the situation was so serious that officers would work with teachers and staff to better educate them on what to look for when it comes to drug paraphernalia.
Said Maj. Campbell, "We are just lucky nobody was killed and there weren't more injuries from this."
