The Affton Post Office at 55 Grasso Plaza will be renamed the Sgt. Amanda N. Pinson Post Office during a dedication ceremony at 11 a.m. Friday, May 6.

Sgt. Pinson, 21, was assigned to the 101st Military Intelligence Detachment, 501st Special Troops Battalion, 101st Airborne Division — Air Assault. She was killed March 16, 2006, during a mortar attack on her compound in Tikrit, Iraq.

Sgt. Pinson, an intelligence officer, was a 2002 graduate of Hancock High School. She was one of the top students in her class, winning several scholarships. Sgt. Pinson cheered with the pompon squad and played basketball and softball at Hancock.

She deployed to Iraq in September 2005 in support of Operation Iraqi Freedom. Sgt. Pinson is the first female soldier from Missouri killed by hostile fire and she is the first female cryptologist the National Security Agency has honored by engraving her name on the Cryptologic Memorial that honors and remembers those who gave their lives “serving in silence.”

On Nov. 5, legislation designating the Affton Post Office building as the Sgt. Amanda N. Pinson Post Office was signed into law by President Barack Obama.

The legislation was sponsored by U.S. Rep. Ann Wagner, R-Ballwin.

Wagner also introduced legislation that was signed by the president designating two other Post Offices in honor of local fallen soldiers — the Post Office at 11662 Gravois Road in Sappington as the Lt. Daniel P. Riordan Post Office and the Post Office at 16105 Swingley Ridge Road in Chesterfield as the Sgt. Zachary M. Fisher Post Office.
