An investigation is underway in Pulaski County to find the cause of two mobile home fires.

Both home fires were on Antioch Lane in Burnside.

The Burnside fire chief says they responded to the first home about 11:30 Friday night.

About two hours later, they were called to a second fire close by.

A neighbor who did not want to be identified says the two fires are a concern for people who live in the area.

One of the mobile homes, that was used as a vacation home, was destroyed.
