A man was found dead Monday inside an air duct at a home near the northwestern Minnesota town of Dent after family members were unable to reach him for several days.

The 40-year-old man was pronounced dead at the scene, the Otter Tail County Sheriff's Office said. His name was not released.

Deputies went to the home just before 10 a.m. after concerned family members reported they had not been able to reach the victim by phone. Members of the Dent Fire Department and paramedics also went to the scene. Responders found the victim stuck in an air duct, the sheriff's office said.

"The death appears to be accidental," the sheriff's office said in its incident report.

An investigation is underway. No other information was immediately released.
