Judge Tosses Abuse Convictions Of Md. Teacher, Citing Bad Lawyering

The Washington Post – By Dan Norse and Nicole Asbury – July 23, 2023

A new trial was ordered for John Vigna, 56, who taught at a Montgomery County elementary school for more than 20 years

…“Trial counsel failed to investigate and prepare Vigna’s defense,” Vigna’s new attorneys, Isabelle Raquin and Steve Mercer, added in court papers, “committed unforced errors which applied to all alleged victims, failed to individually challenge each alleged victim’s motives, and did not exploit their specific weaknesses.”
