PLEASE HELP, they now have nothing!

My Daughter Brittany, granddaughter Audrey and son-in-law were driving back home to Texas after being stuck here in California after Audrey's emergency open heart surgery and collapsed lung. My son-in-law brought everything they owned here to California so they could feel at home here till Audrey got better. So with everything they had, they packed up everything, and they were on their way back and needed to stop to get rest. Well, overnight, thieves stole their U haul, leaving them nothing but the clothing on their backs. Everything to Brittany's name is gone, and all of our Granddaughter Audrey's clothing, toys, and medical supplies, not to mention all past memory momentums that came along with them...Everything is gone!!! A police report's been filed, and yes, they have insurance, but they are on their way home even still, and they won't have anything when they arrive home. PLEASE HELP!
