A two-week trial is expected for a southwestern Michigan public accountant for the slaying of his 70-year-old colleague David Locey.

The Jury selection is Tuesday at St. Joseph County Circuit Court for Andy Brown, who is charged with first-degree murder.

Locey was found dead on Oct. 2 in his office in Sherman Township, near Sturgis. Prosecutors say Brown was in a dispute with Locey at the time of the killing. Court documents show dozens of potential witnesses could testify.

Defense lawyer Michael Hills said the case is highly circumstantial, there was no weapon found and there was no motive.
