Michigan man pleads no contest in failing to store gun that killed 5-year-old grandson

A man blamed for the death of his 5-year-old grandson has pleaded no contest to violating Michigan's new gun storage law , one of the first significant convictions since the law kicked in earlier this year.

Karl Robart faces a minimum prison sentence somewhere in a range of 19 months to three years, according to a deal disclosed Monday in Newaygo County court. He'll return to court in western Michigan on Oct. 7.

Braxton Dykstra was shot and killed on April 1 when a 6-year-old cousin got access to a loaded, unlocked shotgun at Robart's home in Garfield Township, investigators said.

In Michigan, someone who pleads no contest doesn't admit to committing a crime. But it is treated as a conviction for sentencing purposes.

Robart said very little in court. A message seeking comment from his attorney wasn't immediately returned Tuesday. A similar case against Robart's wife still is pending.

Michigan's new gun storage law took effect in February . Firearms must be locked up when children are present. The consequences for a violation depend on the details of each incident and whether someone is wounded or killed.

Braxton's father, Domynic Dykstra, said the length of his father-in-law's prison sentence will be too short.

At least 21 states have criminal laws related to failing to keep a gun away from children, according to the Giffords Law Center to Prevent Gun Violence.

On Tuesday, a Metro Detroit woman was charged with firearm safe storage violation causing serious injury, second-degree child abuse and two counts of felony firearm after a 2-year-old boy she was caring for shot himself with her handgun in Warren .
