Relatives described Margaret Swan as the center of their family after police said she was killed by a stranger on a train.
ATLANTA, Ga. — Margaret Swan was riding home after a family visit when police say a stranger stepped beside her on a MARTA train and stabbed her to death in an attack now moving through state and federal courts.
The 66-year-old Atlanta woman was a mother, grandmother and great-grandmother whose killing has shifted a criminal case into a public reckoning over transit safety. John Elijah Matthews, 25, of Decatur, is accused of attacking Swan on May 30 as the northbound train approached Oakland City Station. He was charged locally with murder and later charged federally with committing an act of violence causing death on a mass transportation system. Authorities said the two did not know each other and that no motive has been released.
Family members have described Swan through the ordinary details of the day she died. Her daughter, Shanae Sams, said Swan had been leaving another daughter’s house and heading home. She was not part of any dispute, relatives said. She was not traveling for any unusual reason. She was using a system she had used before. “Her life was stolen for no reason,” Sams said in a local interview. Relatives said Swan had worked for Atlanta Public Schools and spent years helping hold a large family together. Sams called her a phenomenal person and the family’s rock.
The case file tells a much colder story through times and camera angles. Police reports cited by local stations said Swan boarded the MARTA train at 11:21 a.m. on Saturday. Investigators said Matthews entered about three minutes later and stood near her right side. Federal prosecutors said Swan was seated near the train’s door and looking at her phone. Within seconds, authorities said, Matthews reached into his pocket and pulled out a folding knife. Police said he cut her throat and stabbed her repeatedly in the chest and neck area as she tried to rise and defend herself.
MARTA Police Chief Scott Kreher said investigators saw no contact between Swan and Matthews before the stabbing. “He looked at her, didn’t say anything to her, pulled out a knife,” Kreher said. Authorities said the attack lasted a short time before the train reached Oakland City Station. Local reporting said passengers were trapped inside the moving train for one minute and 34 seconds after the attack began. Some fled and called for help. Officials said Matthews did not turn on other riders. When the train stopped, police said, he walked onto the platform, where officers arrested him shortly afterward.
The arrest warrant account said Swan was stabbed 18 to 20 times. Federal prosecutors said the wounds were in the chest and neck area. Local reports said a responding officer found her motionless in a large pool of blood and began life-saving efforts before medics arrived. She was pronounced dead at the scene. Investigators said Matthews had blood on his clothing and that a bloody folding knife was recovered near him. Prosecutors said the knife was consistent with the one seen in train surveillance video. Those details became central to the federal complaint filed days after the killing.
Swan’s death left relatives with grief and anger over what happened inside the train car. Sams said her mother would not hurt anybody and questioned why nobody helped when passengers heard her screaming. Her granddaughter, Laquita Wooten, directed anger at the accused man and said she did not believe he felt remorse. The family also asked where security personnel were positioned during the attack. Their questions have focused not only on the suspect, but on the short distance between a recorded assault, a crowded transit car and a police response that came after the train reached the station.
MARTA officials said the authority mourned with Swan’s family and called the killing senseless and heartbreaking. The agency said it operates with a dedicated police force of 280 sworn officers and about 12,000 security cameras across its rail stations, buses and railcars. Local reports also said MARTA uses undercover officers, field protective specialists and a real-time crime center during operating hours. Family members said they want more officers on trains and tighter access at gates. Police have said Matthews was listed as homeless, but officials have not publicly said whether he paid a fare or how he entered the system.
The killing also came at a tense moment for Atlanta’s transit network. Kreher said MARTA police had planned to place officers on six-day workweeks as the city prepared for FIFA World Cup events, but the agency started the expanded schedule sooner after Swan was killed. The authority also said it was increasing law enforcement partnerships and adding personnel around the system. Swan’s relatives said those steps came too late for her. Their comments reflected a wider fear among riders after a sudden attack in a public space that many people use because it is part of daily life.
The federal charge adds another layer to the state murder case. U.S. Attorney Theodore S. Hertzberg said Swan’s death affected her family, friends and the broader community. FBI Atlanta Special Agent in Charge Marlo Graham said people using the train system should be safe and free of violence. If convicted on the federal count, Matthews could face life in prison or the death penalty. Prosecutors said the attorney general would decide whether to seek the death penalty. Matthews is presumed innocent unless the government proves the charges beyond a reasonable doubt.
At the time of early court proceedings, AP reported Matthews had waived a bond hearing and had not yet had an opportunity to enter a plea. Federal officials said he remained in local custody and would appear in federal court at a later date. The FBI and MARTA Police Department are investigating. Local reports said he has been permanently banned from MARTA property. Officials have not said whether mental health, prior contact with law enforcement or any other factor is part of the investigation.
For Swan’s family, the next court date will not change the way they describe her final day. They remember her as a woman who was going home, sitting by herself and looking at her phone before violence found her. The next milestone is Matthews’ federal court appearance, which had not been publicly set.
