(KAIR)--The cause of death for a Lansing Correctional Facility inmate is currently unknown.

That’s according to a release Tuesday from the office of Kansas Governor Laura Kelly which says Jamie Gaius Marshall died Monday at the facility.

The release, which states “the cause of death is pending the results of an autopsy," does clarify that the “preliminary assessment indicates the death was not related to COVID-19."

The 43-year-old Marshall had been incarcerated since January 2013 due to two 2003 drug convictions and a rape conviction in 2012.
