I thought a family member said it was a case of choking or something occurring during feeding? Face down on an adult bed "post-Prandial" would be, by definition not during a feeding, but sometime afterwards?
Regardless, it's very sad. He was so stinkin' cute!

Hopefully, moving forward, mom will be cautious with Kason, the remaining twin, and keep him in a crib, with warm pajamas in lieu of lots of blankets, Pillows, crib bumpers, stuffed animals etc. That's the only "something good" I could come up with.
