Kristopher SANDERS, Appellant,
v.
STATE of Florida, Appellee.
No. 2D10-983.
District Court of Appeal of Florida, Second District.
October 5, 2011.
Rehearing Denied November 30, 2011.
James E. Felman and Katherine Earle Yanes of Kynes, Markman, & Felman, P.A., Tampa, for Appellant.
Pamela Jo Bondi, Attorney General, Tallahassee, and Donna S. Koch, Assistant Attorney General, Tampa, for Appellee.
KELLY, Judge.
Kristopher Sanders appeals his conviction for second-degree murder with a firearm. We find merit only in his argument that the trial court fundamentally erred when instructing the jury on the lesser-included offense of manslaughter by act. State v. Montgomery, 39 So.3d 252 (Fla. 2010), mandates reversal.
The State charged Sanders with second-degree murder following the shooting death of Tyrie Gunn. At the conclusion of trial, the court instructed the jury on second-degree murder and on manslaughter by act, a category one lesser-included offense of the murder charge. The court instructed that in order to convict Sanders of manslaughter, the State was required to prove that Sanders "intentionally caused" the victim's death. There was no objection to this instruction despite the fact that at the time of Sanders' trial, the standard jury instruction on manslaughter by act had been amended to clarify that a conviction for manslaughter by act did not require an intent to kill but "only an intent to commit an act which caused [the victim's] death." See In re Standard Jury Instructions in Criminal Cases-Report No. 2007-10, 997 So.2d 403, 403 (Fla. 2008).[1] The jury was not instructed on manslaughter by culpable negligence.
On appeal, Sanders, citing Montgomery, argues that the manslaughter by act instruction *1101 was defective and that its use constituted fundamental error. We agree that Montgomery is controlling. Here, the trial court gave the same manslaughter jury instruction that was given in Montgomery. As in Montgomery, the jury was not instructed on manslaughter by culpable negligence. See Barros-Dias v. State, 41 So.3d 370 (Fla. 2d DCA 2010) (holding that giving the erroneous manslaughter by act instruction did not constitute fundamental error when the jury was also instructed on manslaughter by culpable negligence). We therefore reverse Sanders' second-degree murder conviction, vacate his sentence, and remand for a new trial. See Stoddard v. State, ___ So.3d ___, 2011 WL 3760863 (Fla. 2d DCA 2011); Carter v. State, 53 So.3d 1248 (Fla. 2d DCA 2011); Walker v. State, 46 So.3d 160 (Fla. 2d DCA 2010).
Reversed and remanded.
