NORRISTOWN, Pa. (CBS) — Four people have admitted their role in what Montgomery County prosecutors call a drug ring operating along the Main Line that sold narcotics to high school and college students.

The four, labeled “sub-dealers” by prosecutors, pleaded guilty to numerous drug charges in Montgomery County Court.

Prosecutors say they were hired by the ringleaders of the group to sell drugs — including marijuana, cocaine, and Ecstasy — at five area high schools and three colleges.

Prosecutor Tonya Lupinacci says these defendants will be critical to their case if the rest of the group decides to go to trial.

“All four of these defendants from day one admitted to their role in this organization and today they accepted responsibility through their guilty pleas.  All four have agreed to testify.”

The four are identified as Reid Cohen, Garrett Johnson, Willow Orr, and Dominic Curcio.

Prosecutors say the ringleaders were hoping to create a drug monopoly along the Main Line, supplying drugs to high school students.

Police seized guns, drugs, and money when they were arrested.
