A girl who was critically injured in a mobile home fire this morning is improving. Fire investigators continue to investigate the cause of the fire that claimed the life of a 9-year-old boy.

The fire at 292 Wing Road was reported at 7:15 this morning, when 8-year-old John Parker escaped the blaze and ran out to flag down motorists for help. He was uninjured. His sister, Ashlyn Parker, age 10, was rescued from her bedroom by firefighters and was taken to EMMC in critical condition. Public Safety spokesman Steve McCausland said Ashlyn is being treated for smoke inhalation and her condition is improving. The children's cousin  9-year-old Wyatt Parker of Levant, was killed in the blaze.

Ashlyn and John's parents, Lasey Reidy and John Parker, had left the children alone to run some errands. They arrived back at the house around the same time as fire crews.

Investigators from the State Fire Marshal's office continue to search for the cause of the fire that they believe started in the kitchen. McCausland says there were smoke detectors present in the home but investigators have not determined whether they were working.
