Looking for an old movie title. It is the story of elderly people that are killed in a nursery home (or retirement home). And the killer leaves a bell in their pocket. The actress of investigate the murder after her aunt is killed is blonde. She looks like Cheryl Ladd but not sure if its her. Would like to have the title of that movie It played on the television years ago. Not sure if its was on dvd or vhs. Thanks for your help.
