A man being held at the MacDougall-Walker Correctional Institution was found dead Thursday morning.
The Connecticut Department of Correction says Christopher Root, 29, of Old Saybrook, was found unresponsive near a pool of vomit in his cell.
Root's cellmate had alerted staff about the situation around 12:30 a.m.
The DOC says responding staff immediately initiated emergency and life-saving measures, with continued help from responding paramedics.
Despite the attempts to resuscitate Root, he was ultimately pronounced dead at 1:18 a.m.
The State Medical Examiner's Office is investigating a cause of death.
Root was being held on a first-degree strangulation charge with bond a $1,501,100.
MacDougal-Walker is currently locked down.
