And according to Diaz-Cobo, beyond Liam wanting to impress his friend, there just isn't any physical evidence to prove what Liam said in that conversation was true.

During cross-examinations, he asks each investigator that takes the stand if they found any kind of physical evidence that could prove Sarah was harmed.

They all said no.

And again, the biggest piece of physical evidence missing from this case is a body.

Since no body was recovered, could investigators really prove that Sarah was thrown over the Belmar Bridge?

Could anyone really be sure that Sarah was even dead?

After four weeks of trial, the prosecution rests.

Now it's the defense's turn to call up their bench of witnesses.

And they start with someone who might be their star witness.

Someone who the defense argues could put into question everything the court's heard so far.

Craig Hetzel is a contractor and a Neptune City local.

He has dark gray hair and a strong build.

He says he's been a handyman, working along the Jersey Shore for almost 50 years.

Toward the end of 2016, he testifies that he was helping his son get to work every morning.

They had a routine.

Craig would hit the road by 4.30 a.m., pick up his son, then head to work together.

They crossed the Belmar Bridge every day to get to the highway.

They took their usual route.

He tells the jury there are barely any cars out at that time.

Occasionally, he'd see a homeless person walking around.
