VIENNA, Md. – Maryland State Police homicide investigators say they have made an arrest in connection to an 18-year-old cold case involving the murder of a Somerset County correctional officer.

According to police, 46-year-old John Ingersoll of East New Market was taken into custody shortly after 11 a.m. Friday, at 9544 Black Dog Alley in Easton. Ingersoll is charged with first and second degree murder, along with other related offenses, in connection to the June 4, 2001 murder of 31-year-old Gregory Collins.

Collins was reported missing at around 4 p.m. that day after he did not return home from his evening shift as a correctional officer at the Eastern Correctional Institution in Princess Anne. A Maryland State Police trooper that responded to the report found a wooded area along Indiantown Road, one mile east of Route 331, where it appeared that a vehicle had left the roadway. Further investigation of the area led the trooper to find Collins unresponsive inside of his truck.

Ingersoll is currently being held at the Dorchester County Detention Center pending trial.
