• Luigi Mangione is being held without bail in the NYC murder of UnitedHealthcare CEO Brian Thompson.
• On his 2nd Christmas in jail, he'll be served what a former detainee calls the year's best meal.
• The roast Cornish hen is a "delicious little item" on an otherwise dire day, the ex-inmate said.

On the first day of Christmas — also known as December 25 — partridge is not on the menu for Luigi Mangione. But another exotic bird is.
