how to find out about someones death?

I have been married to this man Sam for 9 years and 3 months. He died May 7,4 days ago, he was a veteran and was drawing va pension and I was included on his pension. What does this mean? Do I still get to receive his pension or maybe his social security? I am disabled, but part of my ssi was taken because of the money I received from Sam. We are still very much married. His family cremated him before even contacted me. What now..any help or advice appreciated. Thank you! I only live on 368 to 392 dollars each month.
