An investigation is underway after a person was found dead inside a garage after South County Fire units put out a housefire on Wednesday. Crews responded to a house fire in the 15300 block of 25th Drive SE in Mill Creek just before 11:30 a.m. When they arrived, they saw smoke and flames coming from the garage of a two-story house. Crews knocked the fire out in about 10 minutes and were able to contain the fire in the garage. A man was found dead in the garage when crews were able to get inside. It's unclear if the man died as a result of the fire or if he was dead beforehand. The Snohomish County Medical Examiner will identify the victim and determine a cause and manner of death. No one else was home at the time, and no firefighters were injured. The cause of the fire is unknown.
