The trial for a man accused of killing Niles couple John and Carolyn Tarwacki is scheduled to begin Tuesday in Cass County Circuit Court.

Keith James Lintz, 28, is charged with two counts of first-degree murder. If found guilty, Lintz would face mandatory life in prison without the possibility of parole.

The trial will begin with jury selection Tuesday morning. More than 100 potential jurors are expected at the Cassopolis courthouse.

The Tarwackis were found dead in their home on Carberry Road in Milton Township on the morning of Feb. 5, 2010. According to autopsy reports, John and Carolyn were both stabbed multiple times and shot twice.

Police received 725 tips and interviewed 381 people in four states before arresting Lintz in October 2012 in Niles.

The case is being prosecuted jointly by the Michigan Attorney General’s Office and the Cass County Prosecutor’s Office.

No motive for the murders has yet been released, but a motive could come out during opening statements.

The trial is expected to last two to three weeks.
