The Corrections
Kepu is a member of the Killer Beez, gang and reports arose that claimed the death was a gang-ordered hit, whilst prison staff members were well aware of threats made against Palmer. The Corrections Department denied the claim made by these reports, stating that an internal investigation had found that prison management and staff were not at fault. Palmer's mother, Ada Palmer, disagreed with the findings of the Corrections Department's investigation. It was reported that Ada Palmer said, "They said it was an accident... it is a cover-up."
