A Marshalltown murder trial commences this week at the Marshall County Courthouse.
Jury selection will begin today for Amarrion Demeir Isom, 21, who is charged with the first-degree murder of Isaiah Forest, 27, on March 17, 2023.
Isom, who is represented by attorney Aaron Siebrecht, pleaded not guilty on March 29.
Marshalltown Police Department Chief Mike Tupper said there are many variables when it comes to selecting a jury. If members of the jury are determined today, he said it is possible opening arguments will then begin.
Instructions for the jury state the case must be proven that Isom shot Forest; Forest died as a result; Isom acted with malice aforethought; and Isom acted willfully, deliberately, premeditatedly and with a specific intent to kill Forest.
If all of the elements can be proven, the jury is asked to find Isom guilty of first-degree murder. If one of the elements cannot be proven, then Isom should be found not guilty of first-degree. The jury will then consider a second-degree murder charge.
An investigation conducted by the Marshalltown Police Department and Department of Criminal Investigations revealed Forest’s death arose from a dispute over a debt with Isom. Law enforcement found three separate witnesses, and one of them said Isom went to Forest’s Boone Street residence door with a pistol grip shotgun, raised it and pulled the trigger.
Another witness said that afterward, Isom allegedly disposed of “a rolled-up rug that contained multiple guns,” including the murder weapon.
The third witness told authorities they had a conversation with Forest on the telephone minutes before he was shot.
Tupper said the law enforcement officers involved did a good job investigating the case.
“I am proud of the work they put in bringing this case forward,” he said.
In a separate incident, Isom was charged with robbing a woman at gunpoint near Center and Grant streets on March 6, 2023.
He has been held in the Marshall County Jail on cash only bonds of $1 million for the murder and $50,000 for the robbery.
