Buriel for my 16 yr old son

I'm raising money to bury my son that was shot and killed while with his suppose to be "friends"on Saturday February 3,2018. They say it was an accident but waited over an hr before calling the police for help and destroying evidence in the process. I don't believe in my heart that my son shot himself and they are covering something up. I'm very appreciative to any and all help. Thank you all in advance for all your help.
