El Chapo has remained virtually invisible since his escape from a Altiplano Federal Prison in July.
In video footage from his cell, El Chapo appears to slip into the shower, but in reality he slips out of the prison and into a tunnel in which he made his escape.
El Chapo remains a ghost, but his son may (or may not) have given away El Chapo's location via Twitter.
El Chapo's son, Alfredo Guzman, posted a photo of himself sitting and relaxing at a table with two men whose faces have been obstructed with emoticons.
One of the men might look a lot like El Chapo.
The caption, translated, reads, "Satisfied here, you already know with whom."
The tweet is tagged with a location reading Costa Rica.
However, Costa Rica could be the South American country or a small town in Mexico's Sinaloa state with the same name.
It also could be neither.
According to Phil Jordan, who spent more than 30 years with the DEA and was willing to give his opinion on the matter, Alfredo isn't as smart as his dad.
He said, "One of the most intelligent traffickers has been Chapo. His son is not the brightest star on the Christmas tree. The best recorded intelligence on the son is that he doesn't have his father's intelligence."
He added, "But I caution this could be a diversion to throw off authorities."
Marco Monge, a spokesman for Costa Rica's Office of Judicial Investigation, remains hopeful that it's the town, not the country.
He said, "We're aware of the picture that has surfaced, but we believe the Costa Rica they're talking about is not in our country but a town in Mexico."
It's pretty clear that El Chapo had help with his latest jailbreak, just like with his previous one. With help going that far up, will he ever be caught again?
What do you think the tweet from El Chapo's son indicates?
