Prosecutor agrees to let a second man on Floridaâs death row do DNA testing Henry Sireci, like Tommy Zeigler, has been on death row 45 years  Published 2 hours ago A second inmate on Floridaâs death row has been granted DNA testing by the Orange County state attorney. Henry Sireci, 72, had sought the testing for almost two decades. Earlier this month, State Attorney Monique H. Worrell agreed to grant his request. Worrell also is supporting DNA testing in the case of Tommy Zeigler, 75. Both men have been on death row since 1976. They faced the same prosecutor and judge in their original trials, and now-discredited scientific evidence swayed their juries.
