Yep, that's former One Tree Hill heartthrob Chad Michael Murray rocking the crew cut, 'stache and steely glare of an LAPD cop. The actor guest stars as Officer Dave Mendoza in the first two episodes of Southland's new season (premiering February 13 on TNT).
"Mendoza's a free spirit who doesn't take anything too seriously," Murray says. "He even gets the uptight Ben Sherman [Ben McKenzie] to relax a bit." On this intense show, that could be a big mistake.
