"I've just been numb lately because I have to keep, I have to keep going, because I have to speak for him," said Patricia Compte, mother of the victim.
Armstrong was on a skateboard, crossing against the light at the City Drive, when a car struck him in a crosswalk just before midnight.
Police have little to go on. The car that hit him is described as a 2000 to 2005 silver Honda or Toyota sedan
"The suspect has probably told somebody. It's hard to keep this kind of thing a secret," said Sgt. Dan Adams from the Orange Police Department.
Because Armstrong was crossing against a light, it was likely no charges would have been filed, but now, the driver is facing a felony hit-and-run charge.
The victim's mother said she's hoping the driver will come forward.
"I know that this is a huge burden for them to carry around," she said. "And next time it may be one of their loved ones, and nobody should have to go through this."
Anyone with information is urged to call the city of Orange traffic division at (714) 744-7460.
