State v. Campbell, 149 Conn. App. 405

Kevin Campbell was convicted of murder with a firearm after a June 27, 2008 club meeting in Torrington where a confrontation with victim Roland Lagasse escalated to a shooting.
Campbell claimed he acted in self-defense or unintentionally discharged the gun during an attempt to stop violence.
The trial court charged the jury on murder and the lesser-included manslaughter offenses, and the verdict was murder with a firearm.
Campbell challenged the jury charge as improper marshaling of evidence, the missing-witness argument, preclusion of two defense experts, and prosecutorial impropriety.
The appellate court reviewed for harmless error and generally upheld the conviction, finding some trial-court errors harmless and some others reversible in part.
Campbell was sentenced to a total term of 40 years’ imprisonment (35 years plus a five-year enhancement) for murder with a firearm.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Was the jury charge’s marshaling harmless error?	Campbell argues the court’s summarization biased the jury against him.	Campbell contends the marshaling unfairly emphasized the State’s theory.	Harmless error; the charge as a whole did not mislead the jury.
Did the court abuse discretion by allowing a missing witness argument?	Campbell claims the State failed to prove Campbell’s availability and the argument was improper.	State asserts availability was shown and argument permissible to reflect case weakness.	Abuse of discretion; harmless error; verdict not swayed.
Did the court properly preclude defense experts Morgan and Danas?	Morgan and Danas would have offered specialized testimony on mental state and firearm safety relevant to intent.	Experts’ testimony was within scope of defense theory and probative to self-defense/intent.	No reversible error; court did not abuse discretion in excluding both experts.
Did the prosecutor’s remarks about self-defense vs. accident amount to prosecutorial impropriety?	State’s rebuttal statements muddied the defenses and misled the jury.	Remarks accurately framed the mutually exclusive nature of accident and self-defense.	No due process violation; remarks, viewed in context, did not deprive Campbell of a fair trial.
