Hayden Panettiere’s last moments: Ex-boyfriend and brother react differently as medics tried to save star

Hayden Panettiere's sudden death has already sent shockwaves in the industry, but as new details emerge, a full picture is slowly but gradually developing.

Now, multiple media outlets are reporting that Brian Hickerson -- the on-again, off-again boyfriend of the late star -- was present at the scene with his brother, Zack Hickerson.

Reports quoted the police incident report stating both brothers displayed divergent reactions during emergency crews attempting to revive Panettiere inside the South Carolina apartment.

Accounts from Matthew Bryan, the responding officer, initially described Zach as "very emotional."

In contrast, Brain reportedly said he did not show much visible emotion.

However, the responding officer's alleged account showed only the responses of the Hickerson brothers while emergency medical workers were treating Panettiere, and not until paramedics declared her death.

Though Bryan's body camera recorded the entire episode, the footage has not been released publicly.

Meanwhile, Panettiere was pronounced dead on Aug 16 after an emergency call described a person having a cardiac arrest.
