There’s a person of interest

Authorities say they have a person of interest in a 2010 double homicide in southwestern Michigan.  The Michigan attorney general’s office is handling the investigation into the deaths of 39-year-old Carolyn Tarwacki and her 42-year-old husband John Tarwacki.  No charges have been filed and the person of interest wasn’t being identified.  The Tarwackis were killed Feb. 5, 2010, at their home in Cass County’s Howard Township, near Niles.  They worked in Stevensville at Quinlan & Fabish Music Co., formerly known as Blessing Music Co. They supplied instruments, gear and maintenance contracts to music educators throughout Berrien and Cass counties.  (AP)
