CHICAGO (WLS) -- Jaden Blake's mother said he was a thriving 20-year-old, a sophomore at Grand Valley State University in Michigan and a stellar pole vaulter.They gave them snacks, and then they told them all of the different ways one unit of blood could help so many people.But in November, right before the holidays, Jaden was in a car accident that landed him in the hospital for more than a week."His mother's request to us was to give that blood back, and at the very minimum I can make that happen," said family friend Kia Horton.Blake said more than 70 people signed up to give blood at the CSO Multiplex in Hyde Park Wednesday."
