Now a task force of local police and federal agents say they've cracked the case.
Detroit Police Chief James Craig announced a major bust in a string of ATM robberies across metro Detroit that started in 2013.
"The good news is that we have the core group in custody and we're confident this will have an impact in eliminating these types of crimes," Craig said.
Four people are in custody including Detroit suspects Edwin Snerling and Christian McGregor.
FOX 2 caught up with a neighbor of McGregor who does not want to be identified.
"This guy was really strange, he was really strange," he said. "I thought he had a lot of friends. Seems like he was doing some illegal activity."
Police say McGregor and the other suspects are responsible for about 17 robberies in several cities including Dearborn, Inkster, Melvindale and Detroit - the last of which where eight of the robberies took place.
"These robberies were distinctive because suspects were stealing vehicles and driving them through windows of local businesses," Craig said.
A task force called the Comprehensive Violence Reduction Partnership combined resources of local police agencies with other agencies like Michigan State Police to catch the suspects.
Two of the ATM incidents took place in Dearborn.
"We're going to make sure that we share resources and intelligence that leads to an arrest of these people," Police Chief Ronald Haddad said. "It shatters the security of a community when they come to work in the morning and see a big hole in the wall."
Police say there are more arrests to be made in this case and they won't stop until they have everyone responsible.
"We think there are additional suspects as we speak," Craig said. "But we're working through that."
