Dateline appears to be involved in various projects and documentaries, including a new series called "The Last Day" and episodes about notable cases such as Mollie Tibbetts and a serial killer on Cape Cod. Other outlets are also exploring "untold" stories, including those related to OJ Simpson, Richard Simmons, and JFK, although it is unclear if these are directly connected to Dateline. The nature and scope of Dateline's involvement in these projects is not entirely clear.
