Sheriff Joe Arpaio fires two top MCSO aides

PHOENIX - Maricopa County Sheriff Joe Arpaio fired two of his top commanders on Friday.

According to public records and MCSO spokeswoman Lisa Allen, Chief Deputy David Hendershott and Director Larry Black lost their jobs based on findings from a six-month investigation by the Pinal County Sheriff's Office.

They were both reportedly told they were fired through letters personally delivered to their homes.

ABC15's Dave Biscobing also went to their homes to get comment. However, no one answered at either home.

The investigation began after another top MCSO official wrote a long memo outlining years of misconduct and criminal allegations. So far, Arpaio's office has refused to release the results of that investigation.

Allen said Hendershott and Black must both legally be afforded a name clearing hearing. And MCSO will grant Hendershott and Black 75 hours to review their findings, according to Allen.

ABC15 obtained a recorded conversation earlier this week from the Attorney General's Office involving strong accusations against embattled Hendershott.

A former MCSO employee is heard in the conversation talking about Hendershott allegedly using money from the Sheriff’s Youth Assistance program to pay off a personal gambling debt he racked up while on a cruise with his family.
