Longtime award-winning L.A. reporter Warren Wilson announced his retirement from KTLA yesterday. When we last heard from him, Wilson had hired Melanie Lomax to press discrimination claims against the station, saying he had gone twenty years without a promotion. But hey, that was a year ago. KTLA's website says that Wilson has served as the go-between in at least 17 surrenders of criminal suspects (the press release yesterday credits Wilson with 22 surrenders.) Franklin Avenue, which reported Wilson's retirement, observes: "Guess they'll have to surrender now to Sam Rubin."
