Mark questions Stephen Hodson, the prime suspect in his wife Joanne's murder investigation, about his whereabouts on the night of October 15th at 10:15pm. Stephen claims he was in bed with his wife, but Mark informs him that the coroner determined Joanne's time of death was actually the night before at 9pm and her body was found in the woods. When Stephen denies this is possible, Mark has him taken into custody for further questioning, citing firm forensic evidence of Stephen's involvement in the case.
