LOS ANGELES (AP) — The top-rated Spanish-language morning radio host known as "El Mandril" left the Los Angeles airwaves about a month ago, but it's not clear why, even to him.

But the LA Times reports the absence may also be because Sanchez's show is the subject of an investigation by research giant Nielsen into allegations of ratings tampering.
