(Memphis) The postmark on the Ricin laced letters sent to U.S. Senator Roger Wicker and President Barack Obama show they came from the United States Postal Service location at 555 South Third Street in downtown Memphis.
“That facility there on Third Street it does handle mail that comes from northern Mississippi, as well as Tupelo Mississippi,” said USPS representative David Walton by phone Wednesday.
