Hamilton County Sheriff deputies are investigating the apparent drowning death of Marilyn Webb, 76, on June 4. Officials said Webb’s grandson found her floating in a pool at her home on Mill Farm Road in Noblesville when he came over to help her clean the pool. Sheriff Mark Bowen said there were no signs of foul play at the scene and no signs of trauma. Police think Webb may have begun working on the pool on her own and somehow slipped in. The investigation is ongoing and an autopsy in pending to try to determine the cause of death.
