Last week, Holloway was charged with two counts of first-degree murder in the death of his parents, Denver and Martha Holloway.

Denver and Martha Holloway are both natives of Pittsburg County. A medical examiner's report says they died of multiple gunshot wounds.

OSBI spokeswoman Jessica Brown said Ross Holloway was alone in his jail cell and there were no signs of foul play. But the OSBI has not made a ruling on his cause of death.
