KALAMAZOO, Mich. (AP) - A southwestern Michigan woman who entered a plea deal after being charged in her 87-year-old mother's overdose death has been sentenced to 5-15 years in prison. Sixty-year-old Susan Kubicek of Portage learned her punishment Monday after pleading no contest to involuntary manslaughter in the May 2017 death of Dorothy Allen. Kalamazoo County authorities say Allen got a morphine dose 80 times greater than what was prescribed. The Kalamazoo Gazette reports defense attorney Ronald Pichlik says Kubicek is remorseful. Kubicek told the court she was trying to follow a nurse's instructions. Kubicek, who'd been caring for her ailing mother, was initially charged with second-degree murder. Stephen Salik, Allen's son and Kubicek's brother, said in a victim impact statement that her actions "put a scar on my heart, on my family's heart." --- Information from: Kalamazoo Gazette, http://www.mlive.com/kalamazoo
