William McCorkle and Andre Clinkscale v. United States, 100 A.3d 116

Triple homicide at a gas station on May 31, 2008; McCorkle and Clinkscale indicted on multiple counts and convicted (McCorkle 14 charges, 144 years; Clinkscale 7 charges, 105 years).
Six eyewitnesses testified; two different semi-automatic pistols used; victims Hough, Jeter, and Mincey shot numerous times; no weapons found on victims.
Harlenia Ray testified about a post-questioning visit warning her not to talk to detectives.
McCorkle admitted shooting Hough and Jeter, claiming self-defense; trial testimony described altercation and firing from the street.
Clinkscale claimed non-participation and sought to introduce Tywon Hager’s proffered testimony that Joyner admitted involvement; court found Hager not credible and thus Joyner’s statement not proven.
Laumer issue focused on admissibility of statements against penal interest and the trial court’s credibility assessment of in-court witnesses; panel upheld the trial court’s ruling and affirmed the judgment.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether Laumer’s first prong remains valid despite later authority.	McCorkle and Clinkscale contend first prong invalidated.	McCorkle and Clinkscale argue Laumer is implicitly overruled.	Laumer remains good law; first prong upheld.
Whether the trial court erred in assessing credibility for admissibility under Laumer.	McCorkle/Clinkscale argue credibility assessment usurps jury role.	State argues credibility assessment necessary for reliability.	Court affirmed exclusion due to lack of made declarant statement.
Whether withdrawal/initial aggressor instructions were required given the facts.	McCorkle sought withdrawal instruction.	No withdrawal basis; initial aggressor instruction appropriate.	Withdrawal instruction not required; initial aggressor instruction proper.
Whether questions about the New Year’s Eve revolver incident and Trey Joyner’s death affected prejudice.	Questions were prejudicial and tangential.	Instruction limiting speculation mitigated prejudice.	Not reversible error given extensive other evidence and limiting instructions.
