ACAPULCO 鈥� Two gang hitmen have admitted to killing 17 of 43 students missing in southern Mexico since last week, a top prosecutor said Sunday.
Inaky Blanco, chief prosecutor of Guerrero state, also said 28 bodies were recovered from a mass grave outside the town of Iguala but that it would take at least two weeks to determine if they are part of the group of missing students.
