The Ada County Sheriff's Office is investigating the death of a male inmate, being held on federal charges on a U.S. Marshal's hold, who died of an apparent drug overdose.
The incident began in the late afternoon hours of March 10, when an Ada County Jail deputy said he had received an anonymous note saying the inmate had illegal drugs in his possession.
A K-9 drug detection dog was brought in to search the inmate's cell but no drugs were found.
Several hours later, in the early morning of March 11, the inmate was reported to be sweating profusely and shaking. Authorities said the inmate initially refused cooperation with medical staff and refused to be taken to the hospital, but nurses determined that he had a dangerously high temperature and he was rushed to Saint Alphonsus Regional Medical Center.
Hospital staff reported that the inmate lost consciousness and went into cardiac arrest before being pronounced dead at 4:05 a.m.
The Ada County Coroner's medical examiner performed an autopsy and found what appeared to be a foreign substance in the inmate's stomach, which has still not been identified.
The inmate, identified as 29-year-old Danny Ryan, tested positive for marijuana and amphetamines.
The inmate had been in custody at the Ada County Jail since March 7.
