Pro tip: If you're planning a bank heist, don't post about it on facebook

Seriously.

What looked on surveillance video to be a classic bank robbery — with armed, masked suspects and terrorized bank tellers — turned out to be an amateurish inside job, allegedly orchestrated by two 19-year-old tellers with the help of a boyfriend and an older brother.

Using an incriminating trail of Facebook posts left by Martinez and her 18-year-old boyfriend, Ricky “Ricko Gee” Gonzalez, detectives arrested four suspects this week on bank theft charges, alleging they made off with $62,000.

Their Facebook pages held not-so-subtle clues: Two days after the robbery, Martinez posted: “IM RICH …” followed by a rhyming expletive.

“WIPE MY TEETH WITH HUNDEREDS …” her boyfriend allegedly posted the day after the heist. He also boasted of wiping another part of his anatomy with $50 bills.

Hundereds, indeed.
