LA CROSSE, Wis. -

The trial for a Minnesota man accused of killing a La Crosse photography store owner and his son last September is set to begin this week.

Prosecutors are expected to argue that outstanding debt from a prior felony case drove Jeffrey Lepsch, a hobby photographer, to rob May's Photo on Sept. 15 and shoot 56-year-old Paul Petras and his 19-year-old son A.J.

The La Crosse Tribune reports jury selection is set for Tuesday and Lepsch's trial is expected to last nine days.

His three public defenders have not revealed the defense.

The 40-year-old from Dakota, Minn. is charged in La Crosse County with two counts of first-degree intentional homicide, armed robbery with use of force and possession of a firearm.

Lepsch remains jailed on a $2 million cash bond.
