Brother-in-law killed by drunk

My sisters husband was killed by a drunk driver on 12/20/2014 on his way to work and its costing my family $6,000 to have a funeral for him. That's just renting a coffin for 2 hours and cremating him. We had no idea the cost of this and were not prepared. This has devastated my sister and 13 year old niece and we are trying to help out as much as we can, but its more than we can afford. Any help would be greatly appreciated, and thank you in advance.
