A Skowhegan woman was seriously injured when fire swept through her mobile home Sunday afternoon.

It was the second fire in Skowhegan in two days to cause serious injuries. Officials are also investigating the cause of a fire that injured a woman and her 4-year-old son Friday night.

On Sunday, the fire was reported around 2 p.m. at the home of 53-year-old Michelle Sweet at 45 Hilltop Drive. She was burned and suffered smoke inhalation while smoking and using oxygen, according to state fire officials. Sweet was able to get out of the house and was found outside near her car. She was flown by Lifeflight helicopter to Maine Medical Center in Portland, where she was listed in critical condition Monday night.

Investigators are still looking for the cause of a mobile home fire Friday night that injured Andrea Curtis, 24, and her son, Tyler Curtis-Benson. Curtis, of 279 North Ave., also was in critical condition Monday night at Maine Medical Center. Her son has been at Shriners Hospital for Children in Boston since he was pulled from the burning mobile home just before 8:30 p.m. Friday by Skowhegan police Officer Tim Williams. Family members say the boy’s condition is improving.

A gofundmepage has been set up for Curtis and her family, as they lost everything in the fire that destroyed their mobile home. Curtis’ husband, Tyler’s stepfather, Brian Armstrong, was at work when the fire broke out Friday night.
