I agree Lazamataz...
Go onto Nextdoor.com and put out a plea to those in your area. ESPECIALLY churches.
If you have a Calvary Chapel in your area I know they have hearts of gold and would come along side you. If at all possible go to the church in person. Or call and have the pastor come to your home.
I am so sorry for the loss of your son.
I posted it to nextdoor.com, but I can’t find my post now
