Three childhood friends killed in a fatal Sorrento crash early Thursday were headed home after a night out in New Orleans, celebrating the end of 30-day work shifts for two of them, both tugboat workers.

Tomas Jones, 23, Austin Kiernan, 22, and Sydney Persac, 19, all from St. Amant, were found dead after their car struck a tree and became submerged in an Ascension Parish bayou.
