Investigator says he found chaotic crime scene

ATLANTA - A homicide investigator testified Monday that he found chaos at the scene where a sheriff&#39;s deputy claims Jamil Abdullah Al-Amin wounded him and killed his partner in a shootout two years ago. <br> <br> Detective Brett Zimbrick said he arrived to find emotional police officers swarming the street where the deputies had been shot and a crime scene that had not yet been cordoned off with police tape. Shell casings in the street had been trampled by officers and run over with vehicles. <br> <br> Fulton County Deputy Aldranon English claims it was Al-Amin -- a Muslim cleric formerly known as &#39;60s radical H. Rap Brown -- who wounded him and killed partner Ricky Kinchen as they tried to serve him with a warrant in Atlanta&#39;s West End neighborhood in March 2000. <br> <br> Zimbrick was called as a witness by prosecutors who are trying to show why shell casings at the scene might not line up with English&#39;s description of the crime. <br> <br> Defense attorneys claim it was a case of mistaken identity and say Al-Amin was targeted because of a government conspiracy that has dogged him since his days as a high-profile Black Panther.
