Police say it's likely the same person or same group of people targeting businesses on the northwest side.
To date, we're talking about at least 13 burglaries over the last two months.
And in each case, the method of breaking in has been exactly the same.
"The way we're alerted, an alarm will go off," says Marana Police Sgt. Jose Alvarez. "We'll get on scene and we'll find that someone has thrown a rock or something through a front window."
That's what's happened now more than a dozen times in Marana since the beginning of January.
Most recently, at the Jim Furrier and Jiffy Lube stores near the corner of Ina Road and Thornydale.
Police say those responsible are in and out in just a matter of minutes.
As of today, there is still no suspect information in any of the cases.
"The thing I'd like to remind all these businesses...if they have an alarm, set the alarm," Sgt. Alvarez says. "If they have any petty cash or boxes...to make sure that they secure them in a safe -- and that way they try to make it a harder target for criminals."
Turns out Marana isn't alone.
Similar crimes have surfaced in Pima County and Oro Valley as well.
Which is why authorities from all three jurisdictions are now working together and sharing information.
Good news is nobody's been hurt thus far.
And there's no record of any confrontation.
But with every new case the stakes are that much higher.
Whoever's doing this realizes several agencies are now investigating.
And at the front of that list is the Marana Police Department.
"We just want to make sure we provide a safe environment for our businesses and our citizens in Marana," Sgt. Alvarez says.
If you see or suspect anything suspicious outside a local business -- particularly after hours --call 911 or 88 Crime.
A reward up to $1,000 will go to the person whose tip leads to an arrest in these unsolved cases.
