MONROE — The death of an inmate Monday at the Green County Jail is under investigation, according to Sheriff Jeff Skatrud.

The 27-year-old man had "no obvious signs of physical trauma." His identity was not released Monday pending notification of family.

Skatrud released a statement about the death at about 5:20 p.m. Monday.

At about 11:40 a.m. that morning, jail deputies "were alerted that an inmate was in medical distress" in the maximum security cellblock at the jail. The jail is located at 2827 6th St., next to the Green County Justice Center.

While deputies attempted life-saving measures on the inmate, Green County EMS and Monroe Fire Department personnel were alerted. The life-saving measures were unsuccessful, and the inmate was pronounced dead at the jail by the Green County Coroner.

The Monroe Police Department is investigating the inmate’s death. An autopsy and toxicology tests are underway.
