Spino, 45, of Waterbury, Conn., died Dec. 29 in Bala Morghab, Afghanistan, of wounds suffered when he was shot while unloading supplies. He was assigned to the 274th Forward Surgical Team, 44th Medical Command, Fort Bragg, N.C. Staff Sgt. Ronald J. Spino, 45, died Dec. 29 in Bala Morghab after he was shot in the back while unloading supplies, the Pentagon said. The military is investigating the shooting and did not say if he was killed by enemy or friendly fire. Spino was a paratrooper and nurse trained to jump into combat zones to treat the wounded, according to reports. He was assigned to the 274th Forward Surgical Team, 44th Medical Command, based out of Fort Bragg, N.C. The Hartford Courant reported that he has previously served in Iraq and had tranferred to Afghanistan a few weeks ago. Gov. M. Jodi Rell ordered flags in the state lowered to half-staff in Spino's honor. "This brave and dedicated medic dedicated his military career to treating the fallen on the battlefield," Rell said in a statement. "Not only did Staff Sergeant Spino care for their wounds, he was trained to take extraordinary risks -- including combat parachute jumps -- to place himself as close to them as possible to provide the very best care. This speaks far more eloquently than any words can do about Staff Sergeant Spino's character and bravery. All of Connecticut joins his friends and family in grieving this terrible loss." Spino lived with his wife in North Carolina, but was originally from Waterbury, Conn., where he attended Holy Cross High School. His friends in his unit said that Spino was a quiet, hardworking soldier with a good sense of humor, the AP reported. Edited to add some details about this medic.
