TULSA, Okla. (AP) — A judge will hear testimony after an internal police report found that an Oklahoma detective "grossly mishandled" evidence while investigating a quintuple death case.
Chief Public Defender Corbin Brewster discussed the internal affairs report during a court hearing last month, saying it appears former Broken Arrow Police Det. Gayla Adcock also violated legal requirements regarding the disclosure of evidence to attorneys.
Brewster said Adcock acquired the evidence in December 2015, but he wasn't made aware any of it was missing until October 2017.
Adcock resigned this year during an investigation over her actions when a hard drive with potentially significant evidence became lost on her watch.
The evidence was related to the case of Michael Bever, 19, who faces murder charges for the 2015 stabbing deaths of five family members and an assault charge involving a sibling who survived the attack, the Tulsa World reported.
Police have said the teen and his older brother, Robert Bever, fatally stabbed their parents and three of their younger siblings in 2015. They said a 2-year-old sister was unharmed.
District Judge Sharon Holmes will hear from Adcock and Assistant District Attorney Sarah McAmis Tuesday to see if evidence related to the internal investigation will be admissible in trial.
The judge said she will likely make a ruling on that issue following the Tuesday hearing.
Michael Bever has pleaded not guilty to five counts for first-degree murder. His trial is scheduled to begin April 16.
Robert Bever pleaded guilty in 2016 and was sentenced to life in prison.
