In an initial statement, ICE said that Arrona-Lara was awaiting deportation proceedings, but did not delve into the reasoning behind his arrest. In a second statement released later on Saturday, the agency said that he is wanted for murder in Mexico. “ICE continues to focus its enforcement resources on individuals who pose a threat to national security, public safety and border security,” that statement read.
Emilio Amaya, the couples’ legal representative, told NBC News that he could not find any outstanding warrants for Arrona-Lara in Mexico. He also criticized ICE’s handling of the arrest.

edit:
ICE original paperwork had no mention of pending Mexican warrant. That was brought up once bad publicity spread like wildfire.
(True or not )
That was why there was no mention of an outstanding warrant because ICE didn't make the claim for hours.
So to be correct, ICE "left out a fairly critical detail "
