From what I gathered watching a news report on this yesterday, when this guy got in trouble in Washington most recently and Arkansas heard about it, they issued a warrant for him for violating his parole which allowed them to hold him w/o bail in Washington. However, for some unknown reason Arkansas then rescinded the warrant causing Washington to have to allow him bail. He bailed out of jail and proceeded to kill those police officers.
Arkansas isn't explaining why they killed the warrant that then dominoed into this tragic event.
Show me the right path, O Lord; point out the road for me to follow. Lead me by Your truth and teach me, for You are a God who saves me. All day long I put my hope in You. (Psalm 25: 4-5)
"For God so loved the world that He gave His only son, that whoever believes in Him shall not perish but have eternal life." (John 3:16)
