A suspect was arrested on the platform minutes after the fatal stabbing.
ATLANTA, Ga. — A fatal stabbing aboard a MARTA train Saturday has shaken riders and left the family of 66-year-old Margaret Swan demanding answers about safety on Atlanta’s rail system.
MARTA police said Swan was attacked near Oakland City Station in southwest Atlanta. The suspect, 25-year-old John Elijah Matthews, was arrested on the station platform shortly afterward and charged with murder. Officials said the attack appeared to be random, and investigators have not reported any prior link between Swan and Matthews.
According to police records, Swan was seated by herself in train car 134 shortly before 11:30 a.m. when Matthews moved beside her. The warrant says he took out a knife, grabbed her and cut her throat before stabbing her repeatedly. Police said video showed the attack lasted only moments. MARTA Police Chief Scott Kreher said the agency was reviewing the case closely and moving officers into more visible positions across the system.
Passengers alerted authorities after the train reached Oakland City Station. Officers intercepted Matthews on the platform with weapons drawn. Police said he followed commands and did not run. A knife was found next to him. A patrol officer reached the train car after a crowd reported that a woman had been stabbed. Emergency crews treated Swan at the scene, but she could not be saved.
Swan’s relatives said she was a loved family member whose daily life included public transit. Her daughter, Shanae Sams, said the family believes the killing should have been prevented. Relatives also questioned whether enough officers were present at stations and on trains. MARTA officials said the suspect is barred from all agency property and said the criminal case will be handled through the courts.
The stabbing has added urgency to a public safety debate already facing MARTA. The system serves Atlanta and nearby counties through rail, bus and other transit service. Officials have pointed to cameras and MARTA police patrols as part of the safety network, while some riders have said they want more officers inside trains and at station entrances.
Investigators are expected to rely heavily on station and train video, witness accounts and the recovered weapon. Prosecutors will decide how the murder case moves forward in Fulton County. As of Tuesday, police had not released a motive, and no evidence had been made public showing that Swan was targeted.
The case now stands with Matthews in custody and Swan’s family awaiting court proceedings. MARTA said it will increase officer presence while the investigation continues.
