From ProPublica, via the NACDL news scan:

In his report, Vorder Bruegge wrote that John Henry Stroman and the robber had similar “overall shape of the face, nose, mouth, chin, and ears.” But Vorder Bruegge stopped short of declaring a match, saying the video and pictures were too low resolution for that.

Nevertheless, prosecutors said in court filings that if Vorder Bruegge took the stand, he would testify that “the photograph is of sufficient resolution to definitively state that the robber is John Henry Stroman.” The judge said the testimony would be admitted if the case went to trial. A week later, Stroman accepted a plea deal.

It wasn’t the first time, nor the last, Vorder Bruegge’s lab results said one thing and the courts were told something different. Court records and FBI Lab files show statements by prosecutors or Vorder Bruegge veered from his original conclusions in at least three cases.
