At approximately 3:00 p.m. on 08/10/01, Guzman confessed to Cronin that he had killed Colvin and had taken a diamond ring and some money from him.  Later, Guzman also discussed the commission of the crime with a cellmate named Paul Rogers in the spring of 1992. 

On 08/12/91, Colvin’s body was discovered lying face down on the bed of his motel room.  The body had nineteen stab, incision, and hack wounds to the face, skull, back, and chest and a defensive wound to the left hand. 

The body was soaked in blood and a large amount of blood was found spattered on the walls.  A bent and twisted samurai sword was found on the light fixture above the bed.  Colvin’s blood alcohol level was determined to be .34 at the time of death.  The cause of death was determined to be loss of blood.

Case Information:

On 11/09/92, Guzman filed a Direct Appeal with the Florida Supreme Court, citing numerous errors, yet the FSC only commented on two: error in not allowing the public defender to withdraw as counsel due to a conflict of interest and error in limiting testimony of two of the defense witnesses.  Due to trial court error in both instances, the FSC reversed the conviction and death sentence of Guzman on 09/22/94.

On 12/27/96, Guzman was resentenced to death.  Guzman waived the presence of jury at either the retrial or the resentence.

Guzman filed a Direct Appeal with the Florida Supreme Court on 01/06/97, raising eight errors:  improper denial of mistrial motion, absence of substantial and competent evidence of guilt, double jeopardy, improper ruling on “various issues,” disproportionate death sentence, improper finding of three aggravating circumstances (HAC; avoiding arrest; and cold, calculated, and premeditated).  The FSC affirmed the conviction and sentence on 01/14/99. 

Guzman filed a Petition for Writ of Certiorari with the U.S. Supreme Court on 03/12/99 that was denied on 05/03/99.

Guzman filed a 3.850 Motion with the Circuit Court on 03/27/00 and amended the Motion on 11/30/00 and 10/15/01.  The Motion was denied on 03/05/02.

Guzman filed a 3.850 Appeal with the Florida Supreme Court on 04/15/02, citing allegations of Giglio violations, by the State permitting false testimony; Brady violations, by the State withholding evidence; the State presenting misleading evidence; and the State giving an improper closing argument.  On 11/20/03, the FSC affirmed the denial of the 3.850 Motion in part, but remanded the case to the Circuit Court to rule on Guzman’s Giglio claim.  On 03/04/04, the FSC issued a revised opinion. 

Guzman filed a Petition for Writ of Habeas Corpus with the Florida Supreme Court on 10/02/02, citing allegations that his waiver of a jury for the penalty phase was invalid and his incompetence to be executed.  On 11/20/03, the FSC denied the Petition.

On 08/27/04, upon remand to the Circuit Court, legal memoranda were filed regarding Guzman’s Giglio claims.  On 09/22/04, the Circuit Court denied the 3.850 Motion. 

Guzman filed a 3.850 Motion Appeal with the Florida Supreme Court on 10/18/04, citing Giglio claims.  On 06/29/06, the FSC affirmed the denial of the motion.
