From the Navy Times:

On Oct. 22, Chiarini, a native of Coventry, R.I., received the nation’s third-highest award for combat valor in a statehouse ceremony attended by Rhode Island’s Gov. Donald Carcieri, two U.S. senators and several state legislators.
…
On the morning of Feb. 10, 2006, Chiarini — who was with Battalion Landing Team 1st Battalion, 2nd Marines, 22nd Marine Expeditionary Unit — was riding shotgun in the third vehicle of a Marine patrol in Anbar when a roadside bomb detonated near the lead vehicle.
