Mexico's investigation into the abduction and apparent massacre of 43 students last year is plagued with errors and omissions and key parts may need to be redone, a review of the evidence shows.

The 43 Mexican students who disappeared four months ago were murdered on the orders of a drug cartel who mistook them for members of a rival gang, the government said on Tuesday, finally confirming the deaths of the trainee teachers.

The wife of a Mexican politician suspected of helping to plot the apparent massacre of 43 trainee teachers in September will be tried for engaging in organized crime, the federal courts authority said on Monday.
