Kristy I am so sorry!
I will be praying for you. This is very traumatic for you I know. My husband was murdered 4 years ago and I too agonized to whether my husband was saved or not. I kept asking in prayer and the Lord answered me. Keep asking and the Lord will provide you with an answer. God looks at the heart yours and your husbands.
Abba we ask for mercy and we ask for an answer for Kristy in Jesus' most precious name! I pray the answer is YES!
