Prince Watson, Alleged iPhone Thief, Charged With Murder Of Woman Who Fell Down CTA Stairs

A Chicago teen has been charged with the March murder of Sally Katona-King, a church deacon who died after a fleeing iPhone robber pushed her down a flight of stairs at the Fullerton CTA stop.

Prince Watson, 17, has been charged with murder and robbery, according to the Chicago Tribune. Watson is currently serving a four-year sentence for a separate iPhone robbery in mid-May.

Katona-King, a receptionist at the Evangelical Lutheran Metropolitan Chicago Synod, was commuting home from work when the theft took place. She ultimately died from multiple injuries related to her fall.

"To die over an iPhone? It's senseless," her son, David King, told the Tribune at the time.

Katona-King maintained her generosity and compassion despite several major tragedies in her life, according to the Chicago Sun-Times. Her first marriage failed, and her second husband was murdered in an armed robbery in 1971. At 29 years old, she was widowed and raising three children alone, according to the paper.

Jeff Drake, an associate to the Bishop at the First Evangelical Lutheran Church where the victim worked, told NBC Chicago that everyone loved Katona-King, and that she was always happy to help others. She reportedly found the church in the 1980's when her 2-year-old grandson died in a fire, and worked there ever since.
