Several people got up Wednesday morning to find their cars torched, and the people responsible are still on the loose. Five cars are so badly torched that they will all need to be replaced.
The fires all took place in Mesa within a one mile radius around Dobson and University, sometime after midnight.
Authorities believe the person who set these fires may have been trying to cause an explosion because some of the fires were started near the gas tanks on the cars.
We talked to some of the people whose cars were destroyed, and they want the arsonist caught before someone gets hurt.
A charred metal shell is all that's left of a Volkswagen Jetta after an arsonist struck a Mesa apartment complex overnight.
"Came out to go to school and I saw the back end of the car charred," says Ty Postal. "It's not even my car - it's my girlfriend's car, I was going to take it to school. I had to go wake her up on her day off to let her know."
A total of five cars were torched between 12:30 and 2:30 Wednesday morning -- including Debbie Kubli's 2007 Hyundai.
"About 2:45 our car alarm was going off - and so my husband got up and he looked out the window right here and the car was on fire," says Kubli.
People living in the complex say they woke up to hear explosions as the intense fires caused the tires to blow out and the windows to shatter.
"It's very unnerving; I know all my family is saying 'Mom, you have to move now.' We've been feeling pretty safe here but this hits pretty close to home."
A brand new Ford Mustang was also destroyed. The owner had it only a few weeks, and now it's headed to the junkyard. Postal's girlfriend's car is too.
"It looks like we were just one of the random cars that got hit. Luck of the draw."
Police searched the area but the suspect got away. They are not sure if this is connected to a string of car fires in Mesa and Chandler in September.
