US soldier’s murder trial begins
The trial of a US soldier charged with the murder of an Italian intelligence agent in Iraq in March 2005 has begun in a Rome court.
The soldier, Mario Lozano of the 69th Infantry Regiment, is not attending the trial, but in Italy the defendant can be tried in absentia.
Mr Lozano is standing trial charged with murder and two counts of attempted murder. He denies the charges.
He [Mr Calipari] was escorting Giuliana Sgrena, an Italian journalist who had just been freed by kidnappers.
As the car approached a road block, US soldiers opened fire.
Calipari, who shielded the journalist during the shooting, was hailed a hero at home, awarded Italy’s top bravery award and given a state funeral attended by tens of thousands.
