The Alaska Department of Corrections says the second of two young inmates’ April deaths in two weeks at its facilities was the result of natural causes.

In a DOC statement Monday night, spokesperson Sherrie Daigle says the state medical examiner’s office has released its final report on 24-year-old Amanda Kernak, who was found dead in her Hiland Mountain Correctional Center cell on April 10.

“The manner of death was found to be from natural causes secondary to complications of severe liver disease,” Daigle wrote. “Out of respect for the family’s privacy and to protect medical confidentiality, the Department cannot release any further details.”

Kernak had been transferred to Hiland Mountain from the Anchorage Jail, where 20-year-old Davon Mosley was found dead April 4. According to DOC, an autopsy on his body revealed internal bleeding from more than a dozen intestinal ulcers.

DOC officials have characterized Alaska’s rate of prison deaths this year as typical, with three inmate deaths as of April versus an average of 10 to 12 annually. Union officials with the Alaska Correctional Officers Association have rejected that claim, however, with business manager Brad Wilson saying DOC’s initial release of limited details on the deaths “has to do with avoiding accountability.”
