We're smarter than that.

Police discovered six dead bodies in a cavern near the tourist resort of Cancun on Sunday, three of them cut open and their hearts removed.

Authorities are investigating the identities of the four men and two women found dead in the natural cave, said Francisco Alor, the Quintana Roo state attorney general.

"They were apparently tortured and their chests were opened to remove the hearts," Alor's office said later in a statement.

Three of the bodies had the letter "Z" carved on their abdomens- a possible reference to the Zeta drug gang, though officials did not make an explicit connection to cartel violence that has plagued many parts of Mexico.

More than 22,700 people have died nationwide in drug violence since late 2006, when President Felipe Calderon sent soldiers and federal police to battle the cartels.

Also Sunday, armed men in two cars barged into a girl's coming-out party in the southwestern town of Coyuca de Catalan, sparking a deadly gunbattle.

Some of those attending the "quinceanera" celebration were also armed and returned fire, Guerrero state police said in a statement. Two partygoers and one attacker were killed, while three people were wounded.

Police have not yet determined a motive, but the area is plagued by drug trafficking.

Ah yes. All the evidence backing up the logical and sensible assumption that drugs are at the root of these problems doesn't fool us. We're way too smart for that. We will never jump to conclusions like the rest of you uneducated, unwashed, unelite masses would. We're far too evolved for that. Instead, we'll demonstrate just how much smarter we are than the rest of you by thoroughly investigating every possible lead that is not on a logical path. In the meantime, forensic evidence will decay, suspects will walk away, and the trail will go cold. Oh well, we did the best we could and more importantly, no innocent (or guilty) people were treated harshly.

Drug dealers everywhere wish to express their gratitude by sending monetary donations but their offers were declined because, "What kind of people do you think we are?". Of course, the donors were later directed toward the investigators' favorite charities... in the investigators' names.
