State v. Ingham, 430 P.3d 931

Background

Ingham admitted to law enforcement he built and detonated explosive devices using beer cans, Pyrodex powder, and fuses to break rocks for minerals; officers found remnants and components.
Prosecutor charged him under K.S.A. 2012 Supp. 21-5814(a)(1) (criminal use of commercial explosives); other counts were dismissed pretrial.
At trial, witnesses and the prosecutor repeatedly described the devices as "bombs," "pipe bombs," and "improvised explosive devices (I.E.D.)."
A law‑enforcement witness testified (over objection) that in his opinion the assembled items made an illegal I.E.D.
Jury instruction equated an "improvised explosive device" with a statutory "commercial explosive;" the jury convicted Ingham and the Court of Appeals affirmed; Kansas Supreme Court granted review.

Issues

Issue	State's Argument	Ingham's Argument	Held
Whether the court abused discretion by denying motion in limine to bar terms like "bomb," "I.E.D.," "pipe bomb"	The terms accurately described the device; probative value outweighed prejudice; common words may be used	Terms are inflammatory and likely to improperly bias jurors by evoking terrorism connotations	No abuse of discretion; use was proper and not shown to prejudice the defense
Whether LEO's opinion that the items "made an illegal I.E.D." invaded the jury's province and violated Sixth Amendment by stating legal conclusion	Testimony was permissible lay/expert ultimate‑issue testimony under K.S.A. Supp. 60‑456; even if error, the statement was harmless given admissions and evidence	The statement invaded the jury's role and improperly stated guilt/legal conclusion	Assuming constitutional error, court held it harmless beyond a reasonable doubt because evidence (Ingham's admissions and physical proof) was overwhelming
Whether the jury instruction improperly equated "improvised explosive device" with statutory "commercial explosive," removing element determination from jury	Instruction mirrored statutory definition and supported conviction on the evidence	Instruction improperly told jury that an I.E.D. is a commercial explosive, usurping jury factfinding	Instruction was erroneous for conflating terms and removing a factual determination, but error was harmless given uncontested evidence proving all elements
Whether court erred by not sua sponte defining "consumer fireworks" (an exception to "explosive")	No evidence supported that device met consumer fireworks definition; instruction unnecessary	Omission deprived jury of a possible acquittal theory and was factually appropriate to give	No clear error; absence of instruction did not affect verdict because record did not support consumer‑fireworks theory
