It is a sad situation.  He was released from a mental institution the day before he killed Ms Little.  He should have been kept there until they knew how the pain medication would affect the anti-psychotic medications, IF he was taking the medications!

"Clallam County Superior Court Judge Christopher Melly ordered Bonner to receive involuntary medication to restore his competency Sept. 15."
Would he voluntarily take the medication if he's ever released?
