Mistrial declared for police officer whose son used gun to kill daughter

The manslaughter trial of a Washington state police officer whose off-duty handgun was used by his son to kill his daughter was declared a mistrial Tuesday, King5 News reported.

A Snohomish County, Wash. judge declared the mistrial, saying the jury had reached an impasse after deliberating for a day and a half.

The shooting took place in March, when Officer Derek Carlile, 31, was on his way to a wedding with his wife and four children. The family pulled over and the Carlile parents left their children in the van as they dropped into a friend’s store.


Within moments, the parents heard a shot. Their 3-year-old son had grabbed the .38-caliber revolver that was in a cupholder and used it to shoot his 7-year-old sister, Jenna Carlile. Jenna was transported to a hospital in Seattle, where she later died.

Carlile was subsequently charged with second-degree manslaughter, the Seattle Times reported.

Carlile’s attorney David Allen told King5 News that he had spoken with the jurors who were split – seven in favor of acquittal, four for conviction and one undecided.

But Snohomish County deputy prosecutor Lisa Paul told the Everett Herald that Carlile had made a series of bad decisions – ones no parent would find reasonable.

Allen said that Carlile had made a tragic mistake but not committed a crime, the Everett Herald reported.

Carlile, who works for the Marysville Police Department, has been on leave since the shooting occurred.
