"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.

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.
