Michael Antwan Jackson, 36, was shot and killed in Miami’s Little Haiti neighborhood on the morning of August 21, 2015. He was pronounced dead at the scene; he was a father of nine and was described as well-known in his community.

The Miami Police Department opened an investigation but initially made little progress. Detectives continued to follow leads and re-examine evidence, and the investigation remained open.

What information do readers who knew Michael or who were in Little Haiti that morning have that might help investigators?
