"Inside the home, troopers found the bodies of four family members: Emily Long (age 34), Ryan Long (age 48), son Parker Long (age 8), and daughter Ryan Long (age 6). A third child, a toddler, was found alive and suffered no physical injuries," New Hampshire Attorney General John Formella said in a statement Tuesday afternoon.

A toddler was found unharmed at the home in Madbury late Monday night when the bodies were discovered, officials said.

Authorities believe Emily Long killed her husband and their two young children before shooting herself on Monday evening. A third child, a toddler, was unharmed.
