ST. PETERSBURG - The case of missing police cadet Kelly Rothwell was scheduled to get more national attention Thursday, when psychic William Constantine was to return to the "Nancy Grace Show" for a second consecutive night. But the segment was canceled at 6 p.m. Thursday.

Grace invited Constantine to return to the show, after time constraints limited his discussion of the missing persons' case. Grace said she will revisit the case soon.

Wednesday night's show examined Rothwell's disappearance on Saturday, March 12th, after meeting a girl friend at Chili's for lunch and grocery shopping at Publix. Rothwell had told her girl friend she was headed home to break up with her live-in boyfriend, David Perry. Perry left Florida for New York, and has declined to discuss Rothwell's disappearance with the Pinellas County Sheriffs' Office, which is investigating the case.
