Asking for prayer!!!

I would like to ask for prayer for a family close to us (The Kurtz's). Two days ago their son (Billy) and his family got into a car accident. Billy passed away at impacted and their daughters and his girlfriend was sent to the local hospital. Their one daughter (Morgan-8 years old) had serious brain damage and we found out today that she passed away. The girlfriend and her other daughter sustained minor injuries. The news and police suspect there is alcohol involved but are doing further examination. This is extremely hard on their family because their eldest daughter passed away 20 years ago from a drunk driver. On top of all of this Billy's brother (Joe) was supposed to get married this Saturday. Please keep them in your prayers!!
