The son of the world’s most wanted fugitive may have tweeted a clue to his dad’s whereabouts.
A twitter account associated with the name “Alfredo Guzman” tweeted a picture of himself with two men whose faces are partially obscured.
The man on the left side of the picture appears to be Joaquin “El Chapo” Guzman, the infamous Mexican drug lord once named “Chicago’s public enemy number one” because of his ties to the Chicago drug market.
The tweet says “satisfied here, you already know with whom.”
A location tagged on the tweet says “Costa Rica.” It is unclear whether that refers to Costa Rica the country, or the town in Mexico by the same name.
Investigators are being cautious as they try to determine whether the location was inadvertently left on or whether it was put there to mislead police.
El Chapo escaped from Mexico’s maximum security prison two months ago after his February 2014 arrest. It was the second time he had escaped from prison — the first being a 2001 escape, followed by 13 years on the run.
The U.S. has offered a $5 million reward for information leading to El Chapo’s arrest. Mexico is offering 60 million pesos ($3.8 million) for information.
