Mia Terrazzas believes she "absolutely" heard alleged domestic violence occurring in Panettiere's apartment

Hayden Panettiere‘s West Hollywood neighbor claims she called 911 at least six times to report disturbances in the Nashville and Heroes star’s apartment. Mia Terrazzas told Inside Edition she believed she “absolutely” heard instances of domestic violence between Panettiere and, allegedly, her on-again, off-again boyfriend, Brian Hickerson.

“I saw her leaving on a gurney,” she said. “Brian was right next to her. And I asked her if she was OK, and it looked to me like she had suffered some type of trauma that looked to be battering. It was clear she was terrified.”

Terrazzas told the TV tabloid that Panettiere seemed like a different person when Hickerson was around, losing her brightness and appearing more subdued.

Hickerson, who has not made any public comments following Panettiere’s death, was with the star in Greenville, South Carolina when she died. A police report, via NBC News, said that he was present with his brother, Zach, the latter of whom showed police a “bag of medication” that Panettiere had been taking. An autopsy reported “no signs of trauma … that would have contributed to the death.” (The DEA is reportedly investigating Panettiere’s death.)

The actress’ mother, Lesley Vogel, brought up Hickerson in an NBC News interview on Tuesday. “This person in her life that we have been trying to get rid of for quite some time was with her at her death, and that was Brian Hickerson,” she said. Despite reports that Panettiere and Hickerson had separated, Vogel said they had been together recently. “There is a lot of history in the past that Brian has enabled Hayden many times, and this is why her father and I had been concerned for a long time about him,” Vogel said.

Panettiere recounted alleged domestic violence against Hickerson, whom she met in 2018 after a rehab stint, in her recently published memoir, This Is Me: A Reckoning. At one point, she wrote, he beat her to the point that she couldn’t leave her apartment for weeks. She later sought a restraining order against him in 2020. In the book, Panettiere described instances of drinking with Hickerson after rehab, which led to other instances of domestic violence.
