7-year old police officer's daughter shot in van by brother who found gun

A 7-year old Marysville, Washington girl was shot by a brother when her brother found the loaded, unsecured gun in the glove box when they were left alone in the family van.  They were both children of a police officer, Derek Carlile.

From the article:

A 7-year-old daughter of a Marysville police officer was wounded Saturday afternoon in Stanwood, when her sibling fired a gun that was inside their parents' van.

Their parents were nearby when the gun went off at about 3:25 p.m. near Stanwood City Hall in the 10200 block of Highway 532, said a statement by the Snohomish County Sheriff's Office, which is investigating. The girl was taken to a hospital.

The girl was administered CPR, but her condition was not noted in the articles.

One should ask:  Why would parents leave a loaded gun in the vehicle with children?  And shouldn't a police officer know better?

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

UPDATE (3/12/12):  The 7-year old has passed away.

UPDATE (3/13/12):  The victim has been identified as Jenna Carlile.  From a follow-up article:

The 7-year-old girl who died after a shooting by a sibling Saturday has been identified as Jenna Carlile, of Camano Island.

Jenna, daughter of Marysville police Officer Derek Carlile, died at Harborview Medical Center in Seattle on Sunday after being transferred there with a gunshot wound to the chest, according to the Snohomish County Medical Examiner's Office.

Carlile has been with the department since 2009.

He has been placed on paid administrative leave pending an investigation by the Snohomish County Sheriff's Office, according to Marysville police.

UPDATE (5/24/12):  The parent, a police officer, is being charged in the shooting.

UPDATE (11/18/12):  The father, Officer Derek Carlile, had a hung jury in his manslaughter case, and the prosecutor has now dropped the case.  He is now free from legal responsibility for the death of his daughter due to his negligence.
