A Minnesota man accused of killing clerks at two Iowa convenience stores in one day has been convicted of first degree-murder in one of the deaths.
Michael Swanson of St. Louis Park, Minn., was found guilty Thursday in the Nov. 15 slaying of 61-year-old Shelia Myers in Humboldt.
Swanson also faces a July trial in the death of 47-year-old Vicky Bowman-Hall, who was shot and killed at a store in Algona the same day.
Defense attorneys and Swanson's family say he was legally insane at the time of the shootings.
A psychiatrist who testified for the prosecution said Swanson had told him he was fascinated by death and thought about killing since he was 13. But the psychiatrist also said Swanson isn't suffering from any type of "diagnosable psychiatric disorder."
