4 year old male Ball Python dies suddenly

I lost my Ball yesterday. I checked on him about 5 am when i was headed to bed like i always do. He was fine, i get up around 12 and check on him he's movin around like normal at about 6 that night he was dead. I don't know what happened. I feed them every 2 weeks, they are handled often, my female is a finicky eater sometimes she just won't eat try again later and she will. I tried to feed her about two weeks ago, she wouldn't eat. I didn't think anything of it. I fed my male he ate no problem. A few days after feeding him he regurgatated i thought it might be because he was stressed out. Next thing i know he's dead. ANY Thoughts as to HOW? He was perfectly healthy before I fed him an now he's gone, my female didn't eat and she's still perfectly healthy. There were no warning signs he was active and healthy.:confused::confused:

What are your temps and humidity? Cage set up?

It's sad and sometimes animal just die without any apparent reason, now the snake in question regurgitated so obviously there was an issue however the only way to figure out what really happened is to put the animal in the fridge (not the freezer) and take him to a herp vet and have a necropsy done.

Are you feeding frozen/thawed? If so, what method do you use to thaw and warm the prey?

Sorry for your loss.
