chicago fire why did casey's mom kill his dad
Matthew Casey Casey is also burdened by his ex-convict mother Nancy, who shattered the family 15 years earlier after murdering his abusive father. He has a sister, Christie, who he grew distant from over their father's death, but they have since mended their relationship. His family still remains a touchy subject and, according to veterans Mouch and Herrmann, there is an unspoken rule within the firehouse that no one is to mention Casey's family or ask him about them.[7] HIs relationship with Gabriela Dawson is a major storyline throughout the series and they eventually marry in the series' 100th epsisode.
