– Vermont State Police say a 5-year-old boy has died two days after his grandmother died while trying to save him from drowning, the AP reports. Authorities say Jaxon Lawrence was pronounced dead at Dartmouth-Hitchcock Medical Center Sunday. Police say Jaxon fell off a toy flotation device in the water of Lowell Lake in Londonderry on Friday. His 55-year-old grandmother, Julie Lawrence, tried to save him, but she also started to struggle. Rescuers and officers found Julie Lawrence and Jaxon unresponsive in the water and tried to resuscitate both. Julie Lawrence was pronounced dead at the scene. Jaxon's 9-year-old brother also tried to rescue him. Police say the boy swam for help and is in good health. (In upstate New York, a 3-year-old boy went missing from his family's home Sunday afternoon and drowned in the Susquehanna River.)
