On Monday, officials also confirmed that there has been one death due to the High Park Fire, The Coloradoan reported. Officials believe they found the remains of 62-year-old Linda Stedman at her house on Old Flowers Road.

The family issued a statement about Stedman that was read by Larimer County Sheriff Justin Smith on Monday night, 7News released part of that statement:

Linda Steadman, mother, grandmother, sister and wife perished in the cabin she loved. As you can imagine, this is a difficult time for the Steadman family, and they ask that they are allowed time to grieve privately. The entire Steadman Family would like to commend all the firefighters and emergency personnel dedicated to saving lives and property.
