If you really “suspect he did commit suicide” then please don’t ever apply to work in law enforcement.
There is no way on earth he killed himself, wrapped himself up in yellow carpet, drove to Fort Marcy park without his car keys, walked down a dirt trail without getting any dirt on his, and then made his gun disappear.
I said the evidence and scenes were manipulated. Do you always have such a reading comprehension problem? The fact that the body was moved is not proof of murder.
