Preston tells the court that they wanted to make Sarah's death look like a suicide.

When Liam and Sarah were alone, Preston testifies that the plan was for Liam to kill her and take her money.

Then he and Preston would throw her body over the Belmar Bridge.

He testifies that they even timed how long it would take to drive from Sarah's house to the bridge and then go home.

So about a month after the first attempt to rob Sarah, Preston tells the jury that Liam put this new, more deadly plan into action.

And a warning, his account of the murder is graphic.

Those horrifying details may sound familiar.

They align pretty closely with what Liam told his friend Anthony Curry when they met in his car while police were recording.

As Preston walks through his version of what happened, the court camera briefly cuts to Sarah's dad, Michael Stern.

At one point, Michael looks down and closes his eyes.

A few people reach over to squeeze his shoulder.

It's harder to see Liam.

He's just a few feet away from Preston as he testifies, but his back is toward the camera the entire time.

We only catch glimpses of his face.

He seems focused as his old friend lays out their darkest secrets.

Preston describes to the jury what happened when they got to the bridge and threw her body over.

This is when the prosecution argues their mission goes from crime to cover-up.

Preston testifies they knew police would question them, so he and Liam had their stories ready to go.

Remember how they both said Sarah had a bad relationship with her father, that she was depressed, and that she wanted to move to Canada to get away from him?

According to Preston's testimony, that was all part of the plan.
