*1185Appellant, Emmanuel Forrest Lockhart, appeals from a judgment and sentence for attempted first-degree murder with a firearm, attempted robbery with a firearm, and burglary while armed. He raises three issues on appeal, as to the first two of which we affirm without discussion.
In his third issue, Appellant asserts that his sentences violate the constitutional prohibition on excessive punishments and we should extend the Graham v. Florida , 560 U.S. 48, 130 S.Ct. 2011, 176 L.Ed.2d 825 (2010), line of cases to adult offenders. Appellant urges us to require sentencing courts to focus on offenders' actual mental age on a case-by-case basis given the rationales of the Graham line of cases and the neurological research showing that the brain continues to develop until the mid-twenties. We affirm on the authority of Romero v. State , 105 So.3d 550 (Fla. 1st DCA 2012). See also McCray v. State , 247 So.3d 721 (Fla. 1st DCA 2018) ; Wilson v. State , 249 So.3d 800 (Fla. 1st DCA 2018) ; Jean-Michel v. State , 96 So.3d 1043 (Fla. 4th DCA 2012).
AFFIRMED .
Wolf, Lewis, and Wetherell, JJ., concur.
