ASHLAND, WI-- The Ashland County Sheriff's Office is investigating three apparent overdoses at the county jail last week.
Two inmates were hospitalized one one day and a third was taken to the hospital several days later, according to the Ashland Daily Press.
All three have since returned to the jail.
All three inmates were housed within the same cellblock. A fourth inmate housed in this block is suspected of smuggling the contraband into the jail.
Authorities did not name any of the inmates allegedly involved.
