Police now say that the 20 Mexican nationals men kidnapped last week in Acapulco had no criminal records and may have been targeted by mistake.
Police confirmed that 19 of the abducted men were mechanics from Morelia vacationing together in an annual ritual.
There has been NO trace of them to date.
A member of the group of visiting auto mechanics from neighboring Michoacan told police that he went into a store and his companions - aged 17 to 47 - were gone when he returned.
Foreign tourists have been avoiding Acapulco in recent years because of growing violence there but it has remained attractive to Mexicans looking for inexpensive vacation.
This mass kidnapping may change that.
