Soccer Star's Mom Kidnapped

Soccer star Sao Paulos mother was recently kidnapped. I would have to say it is because someone hated her minivan. "The mother of Santos player Robinho was held 41 days before being released. Robinho, or Robson de Souza, did pay ransom in that case but it was not known how much." Why anyone would kidnap a soccer players mom is beyond me. If anyone could come up with a reasonable reason I would love to hear why.
