Support for Family After Tragic Accident

My sister's husband was in a nearly fatal car accident on Monday and is in critical condition. She has four beautiful children and she is struggling at the moment. He was the sole provider of his family. He was in a hit and run motorcycle accident and has been in a coma. He is at Long Beach Memorial hospital and the commute to Menifee is taking a big toll. Anything anyone can do to help will be greatly appreciated. Thank you!
