Surveillance cameras caught the crook on camera using a pick-up truck to shatter the glass and find a way into the store on Blackstone.
The store manager of U-Tec told Action News the thief looked like a customer who had been in the shop just a few days earlier.
This time, she was in and out of the business in a matter of seconds.
"Definitely a sad situation to see someone has to come to that to come steal something on Christmas Day.... definitely put a hindrance in our business a little bit, but we're back up and rolling now," said manager David Inman.
Store employees believe the only thing stolen was their server but the woman did leave behind quite a bit of damage to clean up.
They've released the surveillance video to Fresno police in hopes of tracking down the suspect.
