Left a threatening message - I believe it was intended for someone else. The message went something like "I'm going to kill you b***h, you better watch your back, your family's back..."
(504) 715-3360 is a cell phone based in New Orleans, LA
The registered service provider is New Cingular Wireless Pcs, Llc**.
This call is a bit old to be able to contact the JPSO (Jefferson Parish Sheriff's Office) regarding it, but you may want to think about it since a threat of physical violence or death threats are now considered a felony in LA and they will prosecute.
