"I couldn't let him pass away without helping somebody," Marion said.
Across the hospital in Kyle's room, a doctor shared the news that they had found a heart. Denise Wilkerson woke her son, who immediately asked: "Is it Skylar?"
Kyle and Skylar were classmates, but usually traveled in different social circles, occasionally riding bikes together, Denise Wilkerson said. It's all so surreal, it's like something out of a made-for-TV movie, Denise Wilkerson said.
"I wouldn't believe it if I didn't live it," she said.
At a vigil Saturday night, votives that the Wilkersons brought were arranged to spell out Skylar's name. Michael, Zach and Sam Marion called Kyle over. The four draped their arms around one another and posed for a picture. Denise and her husband, Randy, wiped away tears.
The Marions are hoping for a little more good to come from Skylar's death.
Already, his death has prompted the Motor Vehicle Administration to review its driver education curriculum, after the issue got traction from a failed attempt by state Sen. Bryan Simonaire of Pasadena to pass a bill requiring a rewrite of the hit-and-run section and a stiffer maximum sentence for hit-and-run drivers.
Skylar's family also hopes to help families of other crash victims quickly raise money for reward funds.
Having a generous reward can help, according to police, but it's more likely a break will come from someone with a guilty conscience.
"Somebody down there truly knows," said Russell, the investigator. "I don't know what can be done to tug at their heartstrings any more."
