Over a period of months, burglars stole cash, money jars and jewelry from more than 25 homes in Ottawa, Muskegon and Newaygo counties. Each time they took a pillowcase off a bed to carry the loot.
Authorities say the thieves sometimes targeted homes of people who were attending funerals.
Police finally cracked the case this week after a state trooper found evidence at an Ottawa County crime scene that put them on the suspects' trail.
The suspects were arrested after a woman in Muskegon County called police upon finding a cigarette butt on her kitchen floor and jewelry and a pillowcase missing.
The suspects are expected to be arraigned Friday.
