ALTON — Authorities have charged an 11-year-old juvenile with the murder and attempted murder of two adults.

The N.H. Attorney General’s Office said a 911 call was received around 7:30 a.m. Friday morning about a reported shooting at 76 Dobbins Way. Officers from the Alton Police Department responded to the residence and found Lizette Eckert, 50, dead from a gunshot wound and James Eckert, 48, injured from gunshot wounds. James Eckert was transported to Portsmouth Regional Hospital and was listed in critical condition Friday night, authorities say.

The 11-year-old was arrested at around 9:30 a.m. Friday, after a search by Alton police and the Belknap Regional Special Operations Group. The juvenile was charged, under juvenile laws, with one count of second-degree murder and one count of attempted murder.

Authorities didn’t release any addition information about the 11-year-old, citing juvenile laws, or specify what the juvenile’s relationship was with the victims.

An autopsy is scheduled to be done on Lizette Eckert Saturday in Concord.

Anyone with any additional information about this case is asked to contact Detective Sergeant William Bright with the New Hampshire State Police (603) 223-4381.
