People v. Castellano, 42 N.E.3d 914

On Feb. 9, 2008 a gangway fight on South Drake Ave. ended with two men stabbed to death (Rafael Villagrana and Ramiro Landa) and one survivor injured; Ignacio Castellano was arrested at the scene.
Physical evidence (bloody jacket, knife, DNA on jacket/knife/door/light switch, and blood matching victims) tied Castellano and victims to the weapon and scene.
At a bench trial the court acquitted Castellano of one murder count and attempted murder, convicted him of first‑degree murder (Villagrana) and two counts of aggravated battery, and sentenced him to 32 years’ imprisonment.
Castellano testified he and his brother‑in‑law were attacked, he grabbed the brother‑in‑law’s knife in fear and stabbed in perceived self‑defense; police interviews contained inconsistent statements and a recorded interview in which Castellano ultimately said he stabbed but described it as defensive and partly accidental.
The trial court found Cahue’s testimony credible and expressly disbelieved Castellano’s shifting accounts; Castellano was found not to have proved the imperfect‑self‑defense mitigating factor.
On direct appeal Castellano sought reduction of the murder conviction to second‑degree murder, arguing he proved by a preponderance that he had an actual, though unreasonable, belief that deadly force was necessary (imperfect self‑defense).

Issue	Plaintiff's Argument (People)	Defendant's Argument (Castellano)	Held
Whether Castellano proved imperfect self‑defense (an actual but unreasonable belief in necessity of deadly force) by a preponderance, such that first‑degree murder should be reduced to second‑degree murder	The State argued the evidence (witness Cahue, physical/DNA evidence, defendant’s inconsistent and inculpatory statements) disproved the mitigating factor and supported first‑degree murder.	Castellano argued he acted in imperfect self‑defense after being attacked and threatened by gang members; his inconsistent statements resulted from police threats and fear.	The appellate court affirmed: the trial court’s credibility findings (disbelieving Castellano; crediting Cahue) were reasonable and any rational trier of fact could find Castellano failed to prove the mitigating factor by a preponderance.
