The cameraman was identified by the prosecutor’s office of Quintana Roo state only as “J.E.R.V.,” but the local television station Canal 10 tweeted on Wednesday that it lamented the “irreparable loss” of its news cameraman, Javier Rodriguez Valladares.

The second victim was not immediately identified.

An investigation is underway, the prosecutor’s office said in a statement.

At least 12 reporters were killed in Mexico last year, according to free-speech advocacy group Article 19, and the death tally this year is at least six.

In Quintana Roo, long one of Mexico’s safest states, security has deteriorated as gangs fight to control lucrative drug markets, even in resort towns like Cancun.

Two journalists have been killed in the state in recent months, including one who had received death threats for months and reported to the Committee to Protect Journalists that he had been assaulted by local police officers in connection with his work.
