A couple in Roseville is accused of stealing from coin-operated car washes and a laundromat.
Back in June, investigators believe Cynthia Patrias and Robert Miller went to the businesses in the early morning hours, drilled into the locks on the coin boxes and took the change.
Roseville Police talked to witnesses and looked at surveillance video.
After comparing notes with other agencies, investigators believe there is a group responsible for at least 14 similar thefts between February and June, in five counties.
The total loss to victims, including mostly repair costs, is more than $21,000.
Patrias and Miller face charges of grand theft and conspiracy. Charges are also pending against two other unnamed suspects at this time.
