COLE CAMP, Mo -- On June 9, Donnie, Sharon, and Taron Luetjen were found shot to death inside their home here. Police Chief Storm Walker admits the investigation process is slow and sometimes frustrating but insists the case will be solved.

Walker released some new details about the case, including the first actual leads regarding possible suspects. In his weekly column in the Cole Camp Courier, Walker tells of a light colored, older Chevrolet S-10 pickup with a fitted camper shell seen in the area of the home on Sunday, June 7.

There's also a report of someone wearing a white, hooded shirt seen in Water Tower Park. This person was seen across the street from the Luetjens' home on that Sunday afternoon.

The same afternoon, one person told detectives that three or four men were talking to Donnie Luetjen in his front yard.
