A 34-year old female inmate who was found unresponsive Sunday in the Montcalm Co. Jail has died. 

Sheriff Mike Williams says when Amber Lyane Bills of Big Rapids was found corrections officers immediately administered CPR and called for medical assistance but were unable to revive her.

Williams says Bills was being held on two contempt of court charges and a no operator’s license on person charge.

An autopsy has been performed and revealed an undiagnosed perforated ulcer.

The final report from the Medical Examiner is pending. 

The Sheriff has requested that a Michigan Sheriff’s Association MISSION team conduct an external review of the incident.
