However, forThe Hollywood Reporter, “L.A.

I understood why: We’d never had the chance to live our childhoods.”

Jonathan Brandis

“Then when you start getting mail!

I sure never knew it was coming.

It’s not something you prepare for.”

Unfortunately, Brandis' career slowed as the 1990s became the 2000s.

In 2003,the LAPDreported that they’d received a troubling call about the former child star.

Brandis had died by suicide, only 27 years old.

“We couldn’t listen to the voice,” he said.

“Everybody would start tearing up … so it stopped everything for a while.”

He was weeks away from his 20th birthday,” she said.

We moved out of that.

It wasn’t part of our life anymore,” she said.

“This is someone’s child.”
