However, they're holding out hope that Aadan Portillo will someday walk again.
"Seeing him in that condition and knowing that everything has changed for him and us, it's hard," said Ben Portillo, the victim's father. "It's hard to be able to absorb that, when the doctors are telling you he's not going to walk."
The crash happened on Oct. 5 at the intersection of Foothill Boulevard and Etiwanda Avenue in Rancho Cucamonga. Aadan and three of his friends had ordered an Uber ride to go to In-N-Out.
But as their vehicle proceeded into the intersection, they were struck by a reckless driver fleeing from police who ran a red light.
Six people, including the two occupants of the suspect's vehicle, were hospitalized. Aadan's injuries were the most serious.
"We walked in, his eyes were open, he was alert, but the neurologist told us that he was paralyzed," Ben said. "It's hard because he's athletic... He's tall and athletic. He's musically inclined, popular and always surrounded by friends. You'll never see him alone."
Ben said his son is showing strength and positivity to the dozens of friends, family members and classmates who are visiting him in the hospital.
"Aadan's been impacting his friends in a positive way. He's a basketball player, and one of his friends said 'hey I can beat you now.' And he'll say, 'even like this, I can still beat you.' That attitude, that spirit, it's so contagious and it gives us strength."
Aadan's mother, Veronica Portillo, said her son's attitude is giving her strength.
"He's such a determined person," she said. "He's amazing."
Meanwhile, the family has set up a GoFundMe for Aadan.
