I want to know does my boyfriend stand a chance in court.

July 8th, 2019 he had an apparent disagreement with a young man. Him and the young man had a brief struggle and he shot hit. My boyfriend says he took the young mans gun and shot him. So he wasn’t in possession of a firearm. They called it a drug deal gone wrong and claimed it to be self defense so he was never charged for the murder of Markus cantrell. This is Nashville the. July 28th my boyfriend was involved in a car accident with an older lady and the officers claimed they smelled marijuana so they performed a search and they charged. Well today he was placed on a hold meaning he cannot post bond because of a federal warrant This offender is being held for the following reason(s) and is NOT ELIGIBLE FOR RELEASE at this time: Federal Warrant Also Known As (AKA) TRU LEE BOOKER TRU L.
