Michael Swanson

CARROLL, Iowa (AP) — The state has rested its case against a Minnesota man charged with killing a convenience store clerk in northern Iowa. Michael Swanson, of St. Loius Park, Minn., was 17 when he was accused of killing Sheila Myers in Humboldt last November.

The state rested its case Wednesday afternoon during a trial being held in Carroll.  Earlier, the prosecution presented a videotaped police interview showing a tired and hungry Swanson puffing away on cigarettes as he admitted shooting Sheila Myers in the face. Swanson smirked when asked to re-enact what he described as a surprised half-scream, half gasp Myers made when he pulled the trigger. Swanson says he “felt powerful.”

Swanson is also charged with killing another clerk in Algona the same day. His trial in that case is set for July.
