Aaron Brenner

Aaron Brenner was a drug dealer and murderer who appeared in E Malama and who was being investigated for his connection to a drug cartel with the FBI attempting to try him for murder.

Brenner later hired a group of assassins to eliminate Julie Masters before she could testify against him at his trial but thanks to the efforts of Lieutenant Commander Steve McGarrett, Lieutenant Chin Ho Kelly and Officer Kono Kalakaua , all the assassins were either arrested or killed with Masters being able to successfully testify at last much to Brenner's dismay.
