After releasing pop hits and becoming a fixture on Nickelodeon and the Disney Channel, Aaron fell from the limelight as he grew older and faced a variety of drug and legal issues. He was arrested at least twice on drug and DUI charges, entered rehab several times, and had to file for bankruptcy.

On The Doctors in September 2019, he said he had been diagnosed with schizophrenia, bipolar disorder, manic depression, and anxiety and was taking medication to treat the illnesses.

His public feud with Nick started when their sister Leslie Carter died of an overdose in 2012. Aaron criticized his brother for not attending the funeral, and Nick later said it was because his family was “blaming [him] for the death.”

In 2019, Nick and Angel took out a restraining order against their brother. In a statement on Twitter, Nick said his brother had recently confessed “that he harbors thoughts and intentions of killing my pregnant wife and unborn child” and that he was trying to protect his family.

“We love our brother and truly hope he gets the proper treatment he needs before any harm comes to himself or anyone else,” Nick wrote.

In response, Aaron tweeted at the time that he was “astounded” by the charges and did not “wish harm to anyone, especially my family.”

Hilary Duff, who dated Aaron when they were teenagers after he guest starred on Lizzie McGuire, also shared an emotional tribute to him on Sunday.

“I’m deeply sorry that life was so hard for you and that you had to struggle in-front of the whole world,” she wrote. “You had a charm that was absolutely effervescent.”
