Hickerson reportedly traveled with the “Remember the Titans” actress from Los Angeles the day before she was found unresponsive, according to TMZ. The two broke up briefly in 2022, but rekindled their romance the following year. Hickerson’s brother confirmed to police Brian was in a relationship with the actress at the time of Panettiere’s death.
Fox News has learned the Drug Enforcement Administration (DEA) has also been contacted and is assisting with the investigation.

Panettiere’s representatives previously condemned speculation surrounding the star’s final hours and accused outsiders of turning her death into an opportunity to “fuel gossip.”
“Many people who were not close to Hayden are using her death as an opportunity to fuel gossip and speculation about a situation they knew very little about,” Panettiere’s rep said in a statement shared with US Weekly. “It is deeply disrespectful to her memory and to those who knew and loved her and are actively grieving this tremendous loss.”

“If you have legitimate information that could be helpful, please contact law enforcement rather than turning to social media to speculate publicly about something you do not fully understand.”
Panettiere’s team also hinted that key details surrounding Panettiere’s death had yet to emerge.
“There is much more to this story than what is currently being discussed publicly, and those closest to Hayden are actively cooperating with the ongoing investigation to help ensure that the truth comes to light and that justice is properly served,” the statement concluded.
