Gregory Guy Collins

Corrections Officer Greg Collins was shot and killed by a former inmate in retaliation for a perceived grievance after completing his shift at the Eastern Correctional Institution.

Officer Collins finished an overtime shift at midnight began to drive home. He was driving on Indiantown Road in Vienna, approximately two miles north of Route 50, when he was shot one time in the back of the head. His vehicle veered off the road and into a wooded area. When he did not return home, his wife reported him missing. His vehicle was discovered in the woods, still in gear and with its ignition still on, and riddled with four bullet holes.

His murder remained unsolved until 2019 when tips led investigators to a former inmate of the Eastern Correctional Institution. In a recorded conversation, the man confirmed that he killed Officer Collins in retaliation for what was said when he had been incarcerated. On June 7th, 2021, the man was convicted of Officer Collins' murder. In November 2021 the man was sentenced to life without the possibility of parole and admitted that he killed Officer Collins.

Officer Collins was a United States Marine Corps and Maryland National Guard veteran who served three years with the Maryland Division of Correction. He is survived by his wife, daughter, and father.
