Jury selection in the trial of a 20-year-old Oldsmar man charged with the shooting deaths of his mother and her boyfriend was scheduled to begin Monday morning.
Benjamin K. Bishop faces two counts of first-degree murder.
On Oct. 28, 2012, Bishop fatally shot his mother, Imari Shibata, and her boyfriend, swim coach Kelley Allen, with a 12-gauge shotgun while they lay in their bed inside 205 Cedar Key Court, according to the Pinellas Sheriff's Office.
He called 911 and admitted to detectives that he killed them, the Sheriff's Office said.
Bishop has a history of mental illness. He was diagnosed with schizophrenia and has previously been taken into custody under the Baker Act several times. Bishop also pleaded guilty to a misdemeanor battery charge for trying to strangle his mother.
Gun laws prevented Bishop, who has a criminal history, from purchasing a gun. But he recruited a friend to buy the shotgun for him, which he hid from his family, according to records.
In July 2013, he was found incompetent to stand trial and was transferred to a mental facility. Last year, psychiatrists determined he was competent and Bishop was returned to the Pinellas County jail.
