At about noon on Tuesday, June 12, 2018, officers from District A-1 (Downtown) responded to a call for a person with a firearm in the area of 39 Boylston Street. Officers were met by a security officer at that location who advised officers that earlier that day a male attempted to enter the facility with a loaded firearm in his waistband, as well as several magazines and a box of ammunition in his bag. The male produced a Pennsylvania License to Carry ID that the security officer inspected and photographed, but he advised the male that firearms were not allowed inside the facility. The male left with his firearm and stated that he would return later. Further investigation by Boston police officers revealed that the male, identified as 23-year-old Robert E. Goodson of Etna, Pennsylvania, did indeed have a License to Carry; however, it had been revoked one week before. Officers initiated an investigation and advised the security officer to recontact the police should Goodson return.
At about 7:45 AM the following morning, officers received a call from the security officer stating that Goodson had returned, was using the facility, and was not armed or in possession of the large red and black duffel containing the ammunition. After several hours of investigation, Boston police officers were able to locate the duffel bag at a baggage storage desk at the South Station Bus Terminal. Officers contacted the Transit police who maintain jurisdiction over the station, and the officers together determined that the duffel bag would be opened. Upon searching the bag, officers observed and seized the following items:
- One Glock 23 semi-automatic firearm
- Five large capacity magazines, three of which were fully loaded
- Nearly 100 rounds of ammunition
- One black Kevlar ballistic vest, a black neoprene ski mask, and black leather tactical style gloves
At about 4:10 PM that same afternoon, Transit police officers were able to locate Goodson and place him under arrest for firearm related charges.
