Michael Dockrill should not face 4 years in accidental death, lawyer says

The lawyer for a Nova Scotia man convicted in the accidental shooting death of his son argued Thursday the mandatory minimum sentence of four years for the crime is "grossly disproportionate" in this case.

In April,Michael Paul Dockrill, 56, was found guilty ofcriminal negligence causing death and careless use of a firearm.

In June 2011,Dockrill and his son, Jason, were trying to fend off a home invasion at their house in Lakeside when Michael Dockrill opened fire. He said he thought he was shooting at an intruder. He shot and killed his son instead.

Crown and defence attorneys were in court Thursday for sentencing arguments.Nova Scotia Supreme Court Justice Joshua Arnold has reserved his decision on sentence untilFeb.26.

The crime carries a mandatory minimum sentence of four years, as outlined in legislation passed by the former Conservative government.

But Brian Church, Dockrill's lawyer,said such a sentenceviolates Dockill'scharter rights and had a gun notbeen used, his client would not be facing the mandatoryminimum.

"He will live with that knowledge [of killing his son]for the rest of his life," said Church."It is flatly impossible for this court to punish Mr. Dockrill more than he has for his mistake."

Church arguedDockrillshould receivea suspended sentence with three years probation and be made to speak publicly about the dangers of loaded guns.

The prosecution, however, is seeking a sentence of between five and seven years.Crown attorney TanyaCarter said the shooting was intentional, even if Dockrill didn't intend his son to be the victim.

"This tragedy didn't have to happen," she said.
