It was around 5 p.m. when Pauley Perrette walked to her guest house to meet her architect when the attack took place.

The actress shares details of the assault via Twitter.

So, tonight was awful, life changing and I'm only grateful to be alive. It's here: pic.twitter.com/vXIT1pkVRc

Following Thursday’s attack, Pauley Perrette collapsed in the street out of shock. She remembers seeing a man walking his dog in the neighborhood, but he didn’t stop to offer help.

“I texted my friend next door and my church friend cop,” Pauley Perrette wrote. “I immediately drew a police sketch of the guy who was headed towards Hollywood Boulevard with murder in his eyes.”

“We need housing and help for the homeless. We need to support our cops. We need to not walk alone. I need to heal. I almost died tonight,” she added.

Pauley Perrette’s friend tracked down the suspect, David Merck, at a nearby convenience store. He was arrested on Friday morning.

Even though Pauley Perrette helps solve crimes on NCIS, she became the victim of one this week. Hopefully she seeks some counseling to help her through the shock and terror of being an assault victim.
