PHILADELPHIA: The Philadelphia Police Department is renaming its valor medal in honor of a police officer killed while trying to stop a robbery.

Police Commissioner Charles Ramsey called the actions of Officer Robert Wilson III the greatest act of bravery he’s seen in 46 years.

Authorities say Wilson was shot and killed March 5 when two brothers armed with semi-automatic weapons opened fire inside the store where he had stopped to buy a gift for his son and conduct a safety check.

Police say the 30-year-old father of two was getting the game to reward his son for good grades and for his 10th birthday, which was Monday.

Ramsey said at Wilson’s funeral Saturday the slain officer will also receive the department’s medal of honor and a posthumous promotion to sergeant.

Two brothers have been charged with murder in Wilson’s death.

Wilson is the city’s 10th police officer killed in the line of duty in the last 9 years.

During his funeral on Saturday, mourners packed the Palestra sports arena at the University of Pennsylvania and thousands of officers in blue dress uniforms stood silently as his family entered. A large sketch at the arena’s entrance of the 8-year department veteran was covered in mourners’ signatures.
