An American woman employed by the US Embassy died yesterday of a severe head injury. She had been found unconscious near railroad tracks on the western border of Nivky park, a 10-minute walk from the embassy, on Igor Sikorsky Street. Interior Ministry spokesman Artem Shevchenko told Espreso TV police are investigating whether the death was murder or accident. Noting that she was found near the tracks wearing headphones, Shevchenko speculates she could have been hit by a train while jogging.
