NORTH PHILADELPHIA (WPVI) --At just 2-years-old Izzadeen Burgos lost his arm.
His mother, Lisa Campuzano, says he worked hard to overcome that disability his whole life.
"He always wanted to show that he can do things, you know, he needed to do it just because he was missing an arm," said Campuzano.
Campuzano says the 21-year-old was trying to carve out his way in this world.
"He was trying to find himself," said Campuzano.
On July 19, 2015, Burgos was hanging out with friends in his neighborhood of Lawrence and Wingohocking streets in North Philadelphia.
At about 11 p.m. police were called to the area for reports of shots fired.
"Somebody came banging on my door and it was his father's girlfriend telling me that Izzy got shot," said Campuzano. "So then I ran around the corner and once I saw him on the street laying down I just couldn't even go over there, I just dropped right there."
Burgos was pronounced dead at the hospital.
"I mean why would they kill my son," said Campuzano.
The City of Philadelphia is offering up to $20,000 as a reward for information that leads to the arrest and conviction of the person responsible.
"I don't know if anyone knows anything, saw anything of this person, come forward because this is a life and there's other lives that have been taken afterwards," said Campuzano.
