 Although Montaño was not on an assignment at the time of his death, the authorities opened an investigation into the incident.The initial investigation of the situation led to an announcement by the Attorney General of Mexico in July that Montaño's clothing had been caught in the elevator machinery which led to the accident and it was unrelated to his reporting, but his family said that was not correct.The investigation in Mexico City was ongoing as of late 2012, and remains unsolved as of 2017.
