PHILADELPHIA (CBS) — It’s been three weeks since Philadelphia Police Sergeant Robert Wilson III was killed in a gun battle in a GameStop store in North Philadelphia.

His death left behind two young sons.

Today, we hear from one of them as some fellow boys in blue help in the family’s healing process.

With his father’s signature smile, the 10-year-old son of Sergeant Wilson spent Friday opening gift after gift.

“This is a lot of stuff!” Sergeant Wilson’s son said.

On March 5th, police say Wilson was killed taking on two alleged armed robbers at a GameStop in North Philadelphia drawing fire away from patrons inside.

At his funeral he was posthumously promoted to Sergeant and awarded medals for honor and valor for his actions.

He was there originally buying a gift for his son.

“It started off as something for the family on a small scale.”

Radnor Police Lieutenant Chris Flanagan says even without knowing Wilson or his family the men and women some 20 miles away knew they wanted to help.

In the end what started as a drive for just a few toys multiplied by the dozens.

“We just want him to know how many people around the area think about what occurred and how sad we are for the loss.”

All to bring back that signature smile.

“I feel happy. Really happy,” Sergeant Wilson’s son said.

And add a little brightness to the young life of Wilson’s son.

“Thank you everybody!” he said.

Philadelphia Police and The Fraternal Order of Police have also established a GoFundMe page to help Sergeant Wilson’s family in the wake of his death. They’ve collected more than $34,000 in less than 20 days.

Philadelphia Police say members of its department have also established a trust fund for Sergeant Wilson’s family.
