Lawyer's challenge to blood evidence

Mark Alan Winger v. Maher

Updated Nov 12, 2026

In brief

Where it stands
Dismissed

Petition denied.

What it’s about
Mark Alan Winger argued that courts reviewing his claim about his lawyer’s failure to request a Frye hearing to challenge bloodstain-pattern testimony should use state decisions from the time of the lawyer’s conduct, not exclude decisions because they do not fit later changes in state law.
Who it affects
The denial ends Winger’s request for Supreme Court review; it does not decide whether his lawyer violated his right to effective counsel.
