The Florida Supreme Court has rejected the death penalty appeal of a man convicted of disemboweling and partly dismembering a woman in the bathtub of his Miami Beach
apartment.

Michael D. Seibert was sentenced to death in the 1998 murder of
Karolay Adrianza. The court on Thursday unanimously denied all his
claims for relief.

Seibert also was involved in the 1986 knife-point abduction of a
female British tourist across the street from her Miami Beach
hotel. That victim was found the next day naked with head injuries
in a wooded area in Broward County.

State records show that the 43-year-old Seibert is being held in
the Union Correctional Institution.
