The parents of missing 'Growing Pains' actor Andrew Koenig were scheduled to appear on 'Larry King Live' last night, but the couple left the studio before recording their segment of the show, E! reports. Breaking news ate into the Koenigs' allotted time -- and when King introduced the couple toward the end of the show, he found them missing.

"For some reason unbeknownst to anyone, Walter Koenig, the father of the missing Andrew Koenig, and [Andrew's mother] Judy Levin-Koenig... left the studio in Vancouver," King said during the broadcast.
