Sad prayer request

I just received word today of a tragic situation which desperately needs prayer. A man who is friends with one of my sister's in-laws had a daughter that was brutally murdered either today or yesterday I believe. The woman had filed for divorce from her husband and he slit her throat in front of their four year old child. He then took the child and purposely wrecked a vehicle in an attempt to kill both of them. From my understanding the child is ok, but the father is in bad shape. Please pray for this man that he would have the opportunity to give his heart to the Lord before he would die, and that the Lord would help all of the family involved in this.
