Hayden Panettiere 'Absolutely Heartbroken' Over Tragic Passing Of Brother Jansen

Although Jansen wasn't as widely known as his elder sister, the 28-year-old starred in some 2000s movies including Even Stevens, The X's, The Perfect Game, The Walking Dead, Everybody Hates Chris, and Robots.

The cause of Jansen's death is still unknown but the police has ruled out all suspicions. However, the medical examiner's office is still conducting an autopsy.

Jansen and Hayden weren't big expressing their sibling moments but the late actor shared a rare intimate moment with his older sister when she cut his hair earlier this year.

A source spoke to ET Online saying Hayden is heartbroken over Jansen's death because they were very close.

The person added that the 28-year-old struggled with mental health issues and shared it with his family and friends. Before his passing, the actor reportedly engaged in art therapy; hence, the artistic expressions on his Instagram feed.

Hayden supported her brother through his mental health struggle and was ready to help whenever he called.

Unfortunately, it was too late on Sunday, when Hayden learned of her brother's passing. His friends were alarmed when he missed a business meeting leading them to visit his New York residence.

They found him unresponsive sitting in a chair and performed CPR while one of the friends called 911. There's no news about when the actor finally died, whether it was before the EMS arrived or in the hospital.

While there's no sign of foul play, the authorities are considering his history of mental health struggles as a possible cause of death. However, his father, Skip Panettiere cleared the air saying they spoke the day before his death and he seemed okay.

Hayden, 33, is grieving privately as she hasn't posted anything on social media nor commented on Jansen's passing.

However, his girlfriend, Catherine Michie, shared a tribute post saying she was sorry about not being there for the actor in his time of need.

Michie's post further fuels the suspicion that his death is mental health-related.

Hayden and Jansen worked together on three movies including Racing Stripes, Tiger Cruise and The Forger. That was before he added artist to his repertoire.

As an artist, Jansen used the pseudonym, R.A.N.E to sell his pieces. In his Instagram bio, the late actor said he decided to paint his problems and it became his solution.

He donated three percent of his earnings per purchase to a charitable fund supporting Ukrainians.

Since Jansen's passing, fans and friends have shared sweet stories about him in his Instagram comments.

One person claimed they met Jansen over ten years ago and he left a lasting impression with his kindness. Unfortunately, they didn't keep in touch and the poster regrets that.

Selma Blair wanted Jansen to fly with the angels, while another friend thanked him for helping them during a difficult time. The poster, Jonny Woolley, expressed shock at Jansen's mental health struggles saying,

The summary of those condolence messages tells you Jansen was a great individual despite his struggles. Everyone had something good to say about him, especially his treatment of others.
