A detective says a 73-year-old Flint woman admits beating her teenage granddaughter to death with a hammer, then dismembering and scattering the remains 15 years ago. Genesee County Prosecutor David Leyton has charged Lois Janish with an open count of murder in the death of 14-year-old Coral Hall. The girl disappeared in 1998 and her body has never been found.

Leyton spokesman John Potbury says the teen went missing after calling a friend asking for a place to stay and saying she’d been fighting with her grandmother. MLive.com reports that Sgt. Greg Hosmer says Janish apologized for dumping her granddaughter’s body.
