Just read the report- its pretty barebones because anything soft tissue related is now impossible to determine due to the advanced decomp. They determined the gunshot was midsagittal forehead (so not exact midline, off to the side, they do not mention left vs right), fractured multiple skull base bones, and and came to rest inside his brain. A more exact trajectory cannot be determined because the brain turns goopy very soon. No stippling or soot patterns seen, but its impossible to tell due to decomposition. No other skeletal trauma (broken bones, etc).
The coroner came to the conclusion of death due to gunshot wound, but cannot be more conclusive in terms of suicide vs homicide (you mentioned the ruling of suicide, it may be on a different report than this one).
I can't say the report is very telling about manner of death, either. I'm sorry Klingon, it must be very frustrating, especially with all the incompetence surrounding tracing the gun vs testing for fingerprints.
