Duty to preserve police evidence?

This varies from jurisdiction to jurisdiction within the State of Arkansas, and even from Judge to Judge. Generally, I file a motion to preserve evidence within 30 days of arrest. IMO, this puts duties beyond the Brady case to the State. While Brady says the State has a constitutional duty to hand over exculpatory evidence, videos can get deleted due to "document retention policies." You need to immediately contact a proper criminal lawyer. Especially right now with the coronavirus and court closures, I (and everyone else) am having difficulties with the court system and getting things done. It is not the time go tread alone. Good luck.
