The defendant, Takeita M. Locke, was tried and convicted in the Knox County Criminal Court of felony murder and especially aggravated robbery in the death of Chuck Newman. The Court of Criminal Appeals unanimously affirmed both convictions. We granted this appeal to determine if the trial court committed reversible error by failing to instruct the jury on certain lesser-included offenses of felony murder, namely: second degree murder, reckless homicide, and criminally negligent homicide. Additionally, with respect to her conviction for especially aggravated robbery, the defendant maintains that the trial court committed reversible error by failing to instruct the jury on the lesser-included offenses of facilitation of a felony (especially aggravated robbery), aggravated robbery, and robbery. After examining the facts and the law relevant to these issues, we hold that the trial court's failure to instruct the jury on the lesser-included offenses of second degree murder, reckless homicide, and criminally negligent homicide was reversible error. We also hold that the trial court's failure to instruct on the lesser-included offenses of facilitation of especially aggravated robbery, aggravated robbery, and robbery was erroneous, but such errors were harmless beyond a reasonable doubt.
