The ballistics and forensics reports will illustrate just how proximate the gun barrel was to the victim. That will tell us alot about any physical encounter between the two. Don't forget that state statutes state and define the predicates that accrue to a crime. They also state and define what is premeditation and what is intent. If this matter reaches a jury for its deliberation, the charge to the jury will include these statements and definitons. The jury's decision may very well turn on such information despite any emotion-based inclination they may have.
