MEXICO CITY (Reuters) - An independent Mexican commission said on Thursday it found serious flaws in an investigation into the apparent massacre of 43 students last year, dealing a fresh blow to President Enrique Pena Nieto over a scandal that has battered his administration.

The case became a symbol of impunity over disappearances and plunged Pena Nieto into his deepest crisis after the 43 trainee teachers were abducted and very likely murdered by a drug gang working with corrupt police in southwest Mexico last September.
