part of Lou Mumford story for Sunday (Jan. 30, 2011) edition:

The Tarwackis owned a 200-pound mastiff, Wrigley, who was discovered in the house and who was known to be protective of Carolyn in particular. He wasn’t harmed, prompting John Tarwacki Sr. to guess the killer was somebody the Tarwackis and the dog knew. McKnight, too, said the dog’s presence indicated to her the killer had been to the house before.

"He (Wrigley) always met everyone at the door,’’ she said.
Michigan State Police department detective Sgt. Fabian Suarez said investigators went so far as to examine the dog’s teeth, to determine if he may have bitten the killer. They found nothing.
"You’re talking about a gigantic dog. No, it didn’t really surprise me the dog was there,’’ he said. "Some people don’t have fear of animals, or the dog knew who he (the killer) was.’’
Suarez said an examination of the three computers in the couple’s home failed to reveal a possible motive. No illegal drugs were found either, further stumping investigators.
"There really was nothing in their lifestyles that would show these were the type of people that would put themselves in a dangerous situation,’’ he said.
A sketch police released of a "person of interest’’ in the wake of the slayings likely wasn’t the person who killed the Tarwackis, Suarez said. The man depicted in the sketch was observed walking east on Yankee later in the morning, perhaps after the couple was slain, the detective said, but at that point, the car parked on Yankee that had been observed by two earlier passersby was gone.
