The fires broke out just after 12:30 on Wednesday. Firefighters were able to put the fires out within an hour, but nearby homes and apartments were evacuated while they fought the blaze.
Police are looking for 38 year old Sarah Gardner. She's 5'6" and was last seen wearing black shorts, a brown shirt and carrying bags.
The house fires occurred within one block of each other and authorites believe they're related. One was at Colorado and Harriman and the other was at Hillsdale and Delaware.
Police say if you know where Sarah Gardner is to please notify them. They want to talk with her about the fires.
