REYNOSA, TAMAULIPAS – The identity of the man killed in Reynosa Monday night was released.

The city of Reynosa published a statement lamenting the loss of Dr. Oscar Manuel Resendez-Alanis.

Mexico’s federal attorney officer told CHANNEL 5 NEWS he was killed in his vehicle as he waited on the Reynosa International Bridge to cross into the U.S. around 6:30 p.m. Monday.

They believe he may be a U.S. citizen since a U.S. passport was recovered from the scene.

According to a state press release, Dr. Resendez worked in the clinic of Pemex, Mexico’s largest oil company. They believe he was the victim of a possible carjacking, but are working to confirm that through an investigation.

The state press release confirmed he was a resident of Reynosa, but there is still no official confirmation on his U.S. status.
