SPIRIT LAKE, Iowa — Following a bench trial in Dickinson County earlier this month, Allison Decker, 27, was found guilty of the 2020 murder of Angel Bastman, of Lake Park.
Decker was convicted of first-degree murder and sentenced to mandatory life in prison without parole. Also convicted of third-degree theft, she will consecutively serve an indeterminate sentence that will not exceed two years.
Decker was arrested in July 2021, following a seven-month homicide investigation. She and a second individual, Justice Bernston, 25, were placed at the victim’s residence around the time of death via cell phone data and eyewitness accounts.
Shortly after Bastman's death, Decker and Berntson were found in Sioux City, Iowa, in possession of some property belonging to Bastman and her family members, according to court documents.
Though originally charged with first-degree murder, Berntson pled guilty to one count of attempted murder and was sentenced to 25 years imprisonment in June.
