Criminal Minds (9:00 p.m. EST, CBS)

A serial killer commits suicide on tonight’s episode, which I find interesting in and of itself. But it gets more fascinating—he leaves behind clues about a person he abducted…who may still be alive. The team is going to have a lot of work to do to find the possible victim before it’s too late. Football pro Greg Jennings guest stars as an evidence technician on the episode.

Fly Girls (9:00 p.m. EST, CW)

So what’s up with our favorite flight attendants this week? Well, Tasha, Louise and Mandy party down in Miami Beach. Meanwhile, in Marina del Rey, Nikole’s (what an awful way to spell that name) boyfriend stays at the girls’ apartment while looking for a place to live.

However, his “living habits” aren’t up to par for Farrah.

Cougar Town (9:30 p.m. EST, ABC)

On tonight’s episode, Jules (the always sexy Courtney Cox) and Grayson (Josh Hopkins) consider beginning a “friends with benefits” relationship. Meanwhile, Andy (Ian Gomez) hires a nanny; and Bobby (Brian Van Holt) comes up with a unique moneymaking scheme that shares some of the profit with Travis (Dan Byrd).
