Brother of Hayden Panettiere’s ex speaks out: ‘Called 911, Brian gave her Narcan’

As online speculation swirls around Brian Hickerson — an on-again, off-again boyfriend of Hayden Panettiere who was present when she was found in cardiac arrest — his brother is speaking out to tell their side of the story.

Zach Hickerson spoke with TMZ on Friday, almost a week after Panettiere died of an apparent overdose, and following days of increasing scrutiny over Brian’s involvement in her life.

“The truth will come out as the authorities complete and release additional details from the investigation,” Zach Hickerson said in a statement to the outlet. “And that is important because the people who loved and adored Hayden deserve the truth.”

Internet would-be sleuths have popped up in Zach’s comments on social media this week, probing Brian’s behavior and previous conduct.

On Wednesday, Panettiere’s former West Hollywood neighbor Mia Terrazas told “Inside Edition” that she was “terrified” of Brian, and that the apartment complex at one point had signs posted warning passersby to call the police if anyone spotted him. On Thursday, Panettiere’s mother, Lesley Vogel, pointed blame for the actor’s death toward Brian.

But on Friday, Zach said that it was Brian who gave Panettiere a dose of Narcan — a medication that can quickly reverse or reduce the effects of an opioid overdose — after the brothers discovered she was unconscious at the Greenville, S.C., Airbnb where they were staying.

“I want to clarify my involvement in an effort to keep the focus on the fact that we lost one of the most precious individuals on this earth and to allow those that cared about her to mourn without additional noise, chaos, and misinformation being created and propagated by the media as well as the public,” he told TMZ.

Zach told the outlet that he made plans to get lunch and play indoor golf with his brother and the actor after church on Sunday morning. When he attempted unsuccessfully to reach them, he drove to the rental home and “knocked loudly, which apparently woke Brian up from a nap they were both taking on the pull-out couch bed in the living room.”

When they realized Panettiere was unconscious, “I immediately called 911 and Brian gave her Narcan. We then jointly performed CPR while 911 was on speaker until Fire and EMS arrived. At that point we watched as they tried every measure possible to save her life.”

According to a report from Greenville, S.C., police, Zach was “very emotional” as paramedics attempted to revive Panettiere, and Brian “did not become emotional” until paramedics declared that she was dead.

Over the course of Brian’s volatile relationship with the actor, he was arrested multiple times on suspicion of domestic violence against Panettiere. Those include in May 2019 in Los Angeles (charges were later dismissed when prosecutors couldn’t secure a material witness) and again on Valentine’s Day 2020 in Wyoming (misdemeanor battery charges were eventually dropped). Following an eight-count criminal indictment in July 2020 that covered multiple violent incidents between May 2019 and January 2020, Brian pleaded no contest in April 2021 to two felony counts of injuring a spouse or girlfriend.

He was sentenced to 45 days in jail (but served 13 days due to credit for time served) along with four years of formal probation, mandatory domestic violence classes, and a five-year protective order.

Three days before Panettiere’s death, Brian attempted to expunge and reduce his past felony charges but was denied by a Los Angeles judge. He made the same request in July 2025, which was also denied.

“Hayden was one of my dearest and closest friends that I loved and cared about for the last 8 years,” Zach said in his statement to TMZ. “Out of respect for her loved ones, the speculation and sensationalism of her death needs to end until the facts can be released from the investigation.”
