Ryan Widmer is trying for a fourth trial – and his lawyer has filed court documents accusing officials of perjury and a cover-up.

Widmer’s lawyer, Michele Berry, filed a motion today asking a Warren County judge to set aside Widmer’s February murder conviction in the 2008 bathtub drowning of his wife, Sarah.

Berry also wants the judge to grant a hearing based on “newly discovered evidence of false statements, lack of competence and training and outright fraud by the lead detective in this case, former Lieutenant Detective Jeff Braley.”

Further, Berry says Widmer’s former lawyers also made a greivous mistake when they failed to get Sarah Widmer’s DNA tested for Long QT Syndrome, a genetic condition that could have contributed to her drowning.
