He's not answering her phone calls.

The officer turns back to Robin Draper and asks if she told Michael Stern about the bins Sarah brought over.

She says no.

While they speak with Robin, officers are still considering the possibility that Sarah jumped off the bridge.

They're trying to understand her mindset.

The officers get in the car and move on to their next stop, Liam McAtasney's house.

Around 4 a.m., police knock on Liam's door.

The officers step into the house.

It's dark inside.

There are no lights on.

The officer turns on a light, and he can see Liam more clearly.

He's wearing a gray T-shirt and shorts.

He's tall, 6'2", with blue eyes and wavy blonde hair that's messy.

On police body camera footage, it seems like he's just woken up.

Liam and Sarah have known each other since the first grade.

They grew up with a tight circle of friends.

In middle school, their group even had a name, The Squad.

As they got older and graduated from high school, Liam and Sarah still hung out pretty regularly.

Liam says he's been looking for his phone, but can't find it.

This is the first time officers are hearing that Sarah may have run away.
