1987: The Murphy family does not play a significant role in the original RoboCop - only included to establish Alex Murphy as a regular family man. After Murphy's accident, both his wife, Ellen, and son, Jimmy, move away - appearing only in flashback memories. Ellen returns in RoboCop 2, confronting Murphy when she finds out the truth about the RoboCop program, but is turned away by her former husband (so that she can truly move on).
2014: The Murphy family dynamic is a key aspect of Padilha's reboot. It is actually Clara (Abbie Cornish) that allows OmniCorp to enroll Murphy in the RoboCop experiment - in the hopes that he will one day be able to return to his family. Prior to RoboCop's public unveiling he visits with wife as well as son, David, and the two remain instrumental in tethering Murphy to his humanity while he struggles to suppress OmniCorp's programming.
