State v. Banks, 397 P.3d 1195

Background

Banks was convicted by a jury of premeditated first-degree murder for the fatal blunt‑force beating of Daniel Flores in the basement of Steckline Communications; sentence: life with parole eligibility after 25 years.
Crime scene: Flores found face down near the basement door with no defensive wounds, multiple head injuries (four blows), five teeth knocked out, blood spatter low on a wall, and racially/sexually violent writing on the wall aimed at Banks’ ex‑girlfriend.
Circumstantial evidence included surveillance placing Banks near the station that evening, testimony that Banks had been driven there and returned carrying an object, an inmate’s account of Banks’ statements about using a fire extinguisher, and physical signs consistent with a fire extinguisher being used and removed from the scene.
Banks argued the State relied on impermissible inference‑stacking to prove premeditation and that the prosecutor urged unreasonable inferences in closing argument (prosecutorial error).
Banks also contended the district court violated his right to present a defense by excluding three photographs of handwritten notes found in Flores’ car for lack of authentication under K.S.A. 60‑464; he did not attempt to authenticate them at trial.
The Kansas Supreme Court affirmed: (1) the circumstantial evidence permitted reasonable inferences of premeditation without impermissible stacking; (2) closing argument was within permissible bounds; (3) exclusion of unauthenticated writings was proper.

Issues

Issue	Plaintiff's Argument (State)	Defendant's Argument (Banks)	Held
Sufficiency / Premeditation (inference stacking)	Multiple independent circumstantial facts (multiple blows, lack of defense, post‑felled blows, blood patterns, presence at scene) each support an inference of premeditation.	Conviction depends on impermissible inference‑stacking—State asks jurors to chain presumptions to reach premeditation.	Evidence was sufficient; State relied on separately proved circumstances rather than impermissible stacking.
Prosecutorial error in closing argument	Prosecutor’s narrative drew reasonable inferences from the evidence and argued a permissible theory of how the killing occurred.	Prosecutor filled evidentiary gaps with unreasonable factual assertions, amounting to plain error.	No prosecutorial error: closing comments stayed within wide latitude and inferences were reasonable.
Exclusion of defense photographs (handwritten notes)	The photographs were unauthenticated and potentially misleading; State would withdraw objection if defense authenticated them.	Photographs were critical to defense and exclusion violated right to present a defense; notes were found in Flores’ car so should be admissible.	District court did not abuse discretion: defense failed to authenticate writings under K.S.A. 60‑464, so exhibits were irrelevant and properly excluded.
