Knight v. State, 76 So. 3d 879

Knight was convicted of two counts of first-degree murder for the deaths of Odessia Stephens and Hanessia Mullings on June 28, 2000.
During guilt phase, evidence showed Knight lived with the victims and their child; a custody dispute preceded the murders.
Prosecution evidence included Knight’s wet appearance, blood-stained clothing, DNA on Odessia and Hanessia, and eyewitness-style confessions to a jailmate.
Medical examiner documented multiple stab wounds and signs of struggle; both victims were not killed instantly, with Odessia attacked first and Hanessia enduring a later attack.
In penalty phase, Knight presented mitigating testimony about his upbringing and brain-function concerns; jury recommended death for both murders.
Spencer hearing in 2006 and a post-trial sentencing order upheld two aggravators for Odessia's murder and three for Hanessia's murder, totaling eight nonstatutory mitigators.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Mistrial denial after Mullings' comment	Mullings’ statement reflected Knight’s violent background and prejudiced the jury.	Objection sustained; comment curable by admonition; mistrial not required.	No abuse of discretion; mistrial not warranted.
Shackles seen by jurors	Visible shackling could prejudice the jury and require mistrial.	Any view was inadvertent and not prejudicial enough for mistrial.	Brief inadvertent sighting did not require mistrial; no abuse of discretion.
Discovery violations and DNA evidence	DNA testing disclosed later should have triggered Richardson hearing; defense was ambushed.	No discovery violation; evidence was disclosed; Richardson hearing not required.	No discovery violation; no Richardson hearing required; ruling affirmed.
Seat a new jury for penalty phase	Mullings’ testimony tainted guilt phase and necessitates a new penalty-phase jury.	No entitlement to separate guilt and penalty juries; jurors presumed to disregard.	No basis to seat a new jury; no reversal or remand.
Constitutionality of Florida's death sentence statute	Statutory framework violates Sixth Amendment and Ring v. Arizona.	Court has repeatedly rejected this challenge and upholds statute.	Statute constitutional; no relief.
