You might remember Brenda King's Sewing Shop was destroyed by an arsonist in May.
Investigators say two items were stolen from the building prior to the fire being set- a c.d. player and an e-systems computer.
And it's believed they may have something to do with the fire.
So agents with the Bureau of Alcohol, Tobacco and Firearms are now upping the reward to $7,500.
They want information about the arson or the stolen items.
Garett Nelson with the Fire Marshal's Office hopes a higher reward will close this case.
Nelson says, "We're hoping that that might inspire some information, somebody knows something about this and we know we're just asking that you do the right thing and give us information."
If you have any information, you're asked to call the Fire Marshal's Office or CrimeLine at 741-1000.
