Two Ohio children found dead in grandparents' home

(UPDATED -- see below)

Austin Wiseman, age 12, and Blake Campbell, age 9

Two young boys were found dead in the home of their Jackson, Ohio grandparents. From a story about the incident:

Two brothers, ages 9 and 12, were found shot to death inside their grandparents’ home in Jackson County yesterday, and authorities are saying little about what happened.

They did not release the boys’ names, but neighbors identified them as 12-year-old Austin Wiseman and 9-year-old Blake Campbell. Public records show that a woman who lives at one of two addresses involved yesterday, 32-year-old Kelly Lenoir Harris, is the mother of those two boys.

No one would say where she was last night or whether any arrests had been made.

Authorities said the Jackson County sheriff’s office received a 911 call from a cellphone just after 11 a.m. The caller said the two boys had been found dead in an upstairs bedroom. County Coroner Gregory Hawker said this morning that a .44-caliber, six-shot revolver was found at the scene. Hawker said there were other weapons present, but the revolver was the only one loaded. The weapon has not yet been determined to be the one that fired the fatal shots, Hawker said, adding that preliminary autopsy results should be available this afternoon.

UPDATE (6/28/13):   According to authorities, Austin shot and killed Blake before turning the gun on himself.  They were brothers, at the home of their grandparents'.  It's unknown if it was an intentional murder/suicide or if Blake's death was unintentional.  Both were shot in the head.  There were several guns found at the scene, though only the .44-caliber handgun used in the crime was loaded.  From an article:

Authorities determined Thursday that Austin Wiseman, 12, shot and killed his half-brother Blake Campbell, 9, before shooting himself in the head around 11 a.m. Wednesday. 

The boy's grandparents, with whom they lived, came home from an errand and found the dead boys in the Jackson home's bedroom, the Columbus Dispatch reports. .... 

Police have not determined yet if Campbell, killed first by a gunshot to the head from a few feet away, was shot accidentally. Several guns were found at the scene, police said, including a .44-caliber revolver. Authorities have yet to determine if that gun was used in the murder-suicide, but the handgun was reportedly the only loaded weapon 

Who owns the gun - and how Wiseman got his hands on it - remains unclear. The boy's mother, Kelly Lenoir Harris, 32, lives in a garage apartment behind the grandparents' East South St. home. It's unclear where she was at the time of the shootings.

Every gun in the hands of a child must first pass through the hands of an adult.
