Chuck Millar seems to have a history of disturbing behavior, violent outbursts, and threats. According to Millar's ex-wife and ex-girlfriend:
“I will not subject … myself to live on this rollercoaster he calls life, never knowing what we might say or do to set him off into an angry outburst.” 2
“His extreme and violent temper and outbursts that made no sense to me. I have now realized he needs psychological help.” 2
“He is a narcissist and a dangerous one” 2
In 2009, Martin Sheriff deputies responded to a domestic disturbance call at Millar's home. Chuck Millar was yelling, berating, and throwing his wife's belongings out of the house. At one point while trying to get more of her clothes, he “grabbed her by the shoulders and threw her out of the way.” 2 Police noted that he was visibly intoxicated and smelled strongly of alcohol. Millar was arrested for domestic battery and his wife filed for divorce six weeks later, telling the judge she would no “longer be an enabler and let this violent alcoholic verbally abuse and control my life and (redacted; likely “child's”) life.” 1
In 2018 Millar's girlfriend petitioned the court for an injunction for protection against stalking. After dating for a little more than a month, she broke up with him and over the course of 11 days Millar sent dozens of texts and emails. Some of the messages were sexually demeaning. In others, Millar implied that he was tracking her online dating accounts and referenced a domestic battery case from her past. 3
Judge Karen Miller of the 15th Judicial Circuit instructed him to seek counseling and treatment and to stop contacting his ex-girlfriend before dismissing the case.
