A former Princeton University student who was arrested after picking up a packages containing drugs that were shipped to him at the campus mailroom has been sentenced to five years in prison.

Julian Edgren, 21, pleaded guilty to multiple drug possession and distribution charges earlier this year. The Princeton High graduate will begin serving his sentence in November.

Edgren showed up at the Frist Campus Center mailroom at Princeton University in January to pick up parcels and was arrested by the Mercer County Narcotics Task Force.

The U.S. Department of Homeland Security intercepted a package from overseas in mid-December containing approximately seven grams of ecstasy addressed to Julian Edgren at Princeton University. Princeton University’s Department of Public Safety was contacted and reached out to the Mercer County Narcotics Task Force for assistance. Task force officers were assigned as surveillance inside and outside Frist Campus Center in an attempt to detain any individual who retrieved the parcel. Edgren signed for and retrieved the package containing the ecstasy and two additional packages.

Search warrants were executed on one of the additional parcels and Edgren’s dormitory room in Edwards Hall. Psilocybin, commonly known as mushrooms, was found in the additional package. A search of Edgren’s room turned up psilocybin, 31 marijuana cookies, and assorted drug paraphernalia. Edgren was carrying a duffel bag containing about half an ounce of liquid LSD, 55 grams of marijuana, five grams of hashish, 60 Adderall pills, a laptop computer, two digital scales, and $400 in cash, law enforcement officials said.

He was charged with five counts of possession of a controlled dangerous substance, five counts of possession of a controlled dangerous substance with the intent to distribute, one count of possession of a prescription legend drug, one count of a prescription legend drug with the intent to distribute, and one count of possession of drug paraphernalia.

The approximate street value of the seized drugs was $400 for the psilocybin totaling 40 grams, $420 for the Adderall pills, $1,100 for the marijuana, $500 for the LSD, $280 for the ecstasy, and $175 for the hashish.
