A New York City Transit Authority employee was indicted for the murder of his ex-girlfriend after his MetroCard pass traced his whereabouts near the murder scene.
On March 8, Angelique Williams, 29, was stabbed to death as she exited an express bus heading home from work. Her ex-boyfriend, Christopher Stewart, 36, immediately became the suspect. Stewart told authorities that at the time of the murder he had taken the Staten Island ferry to Manhattan, where he boarded the subway and then a bus heading toward Atlantic City.
However, Stewart's MetroCard, which is also his employee ID, showed him heading toward Williams' apartment prior to the murder and then returning home afterwards.
According to New York MTA, MetroCard use can be traced by a serial number located on the card.
Stewart was arrested on March 23, 2001, in North Carolina and brought back to Staten Island. He was subsequently indicted by a grand jury for second-degree murder and other charges.
