Marion Logan Marion Logan was the mother of Callum Logan and the grandmother of Max Turner . She accompanied her son to a mediation session in March 2015 after he got into a feud with Max ' s stepfather David Platt over his son ' s custody . When Callum and David went into the session , Marion began to chat to David ' s mother Gail McIntyre in the reception area and the pair got along well , agreeing that they needed to be the voice of reason with their feuding sons . At a later session , Marion joined in with her son where David was on edge due to the non - appearance of Gail . He barely held it together and blurted out that Callum ' s past criminal record was not behind him and he was still dealing in drugs . Marion , her rose - tinted specs on , accepted that her son had done wrong in the past but he had since put it all behind him . In September , Marion and Callum arrived at Bessie Street School to pick up Max - who had been sent home after being poorly . A couple of weeks later she attempted to contact Callum on his mobile , unaware that he had just been killed by ex - girlfriend Kylie Platt , following his attack on her sister - in - law Sarah . Just over a fortnight later , Marion turned up in the Rovers asking for Sarah and informed her that she feared Callum was missing . Although Sarah explained that they ' d split up a few weeks earlier , she was visibly shaken - still reeling from the previous week ' s events and went outside to get some fresh air . Marion accompanied her back to No . 8 where Marion also received a frosty reception from David and Kylie . After hearing that Max didn ' t want anything more to do with his father , Marion was ordered to leave the house , with David telling her that they ' d be in touch if Callum got back in touch with them . Marion turned up to the house again a month later and began to grow increasingly worried as she still hadn ' t heard from Callum , stating that he ' d never forget her birthday . When she began to question David , Kylie and Sarah as to whether they were hiding anything , this prompted an angry David to throw her out once more . In late - December , David bumped into Marion while Christmas shopping . Marion - accompanied by a police officer - explained how she ' d had her purse stolen and feeling sorry for her , David treated her to a coffee . It was then she revealed that she ' d fallen out with her sister about Callum and had nowhere to go for Christmas . Feeling guilty , David offered to take Max to visit her , and the pair went to her house on Christmas Eve . Marion made a visit to Weatherfield General during the following March , after being tipped - off by Gemma Winter that Sarah had gone into labour , with Callum ' s child . An enraged Sarah told Marion in no uncertain terms to keep away from both her and baby Harry , and threw her out of the hospital room . In May , Callum ' s body was uncovered from its hiding place of the Platts ' converted garage . Marion , believing David to be the killer , confronted him and slapped him across the face . A few weeks later , Marion visited St . Mary ' s Church , and asked the vicar Billy Mayhew if he would conduct Callum ' s funeral . She told Billy about how Callum started to change at the age of 12 , getting in the with wrong crowd and how she hoped he would return to his old self , which never happened . She also told him of her wish that Callum would get justice and his killer would be put behind bars . Billy was put in a difficult position , because he was friends with Sarah and knew what kind of person Callum really was . He also knew details of the murder that Marion and the police were unaware of . Regardless , Billy agreed to conduct the funeral which took place a few days later . However , he walked out partway through the service , feeling too conflicted . Todd Grimshaw talked some sense into him and the service continued . After the service , Marion asked Sarah if she could be involved in her grandchildren ' s lives but Sarah gave her no response . List of appearances . 2015 2016
