An Ohio man convicted of killing his 15-year-old neighbor because he walked on the man's well-kept lawn has committed suicide in prison.
Ohio prison officials say 69-year-old Charles Martin killed himself Friday at the Lebanon Correctional Institution in southwest Ohio.
The Department of Rehabilitation and Correction did not say how Martin died. He had been sentenced to serve 18 years in prison before he could be considered for parole.
Martin had pleaded not guilty by reason of insanity to shooting Larry Mugrage Jr. to death with a shotgun in March 2006. Jurors rejected that argument and convicted him.
At sentencing, Martin said he was sorry the shooting occurred. But he said the teenager knew how much he cared for his lawn and provoked him.
