Affirmed. See Christopher v. State, 489 So.2d 22 (Fla. 1986) (second post-conviction motion fails to show defendant did not know or could not have known of facts supporting his claims at time of initial motion); Witt v. State, 465 So.2d 510 (Fla. 1985) (does not disclose justification for failure to raise issues in first motion); Smith v. State, 445 So.2d 323 (Fla. 1983) (cannot raise appellate issues in post-conviction motion); and, Dobbert v. State, 456 So.2d 424 (Fla. 1984) (may summarily deny successive post-conviction motion asserting additional grounds for claim of ineffective assistance of counsel).
