Mr. Ballin

A woman would answer the door, and when Verriere flashed his badge, she invited him inside.

The woman, whose name was Sophie, had reached out to the police after watching Mark's interview on TV, saying she did have information about Patrick's case.

And so Verriere followed her into her kitchen, and he sat down across the table from her, and he turned on his recorder, and he told her to just start from the beginning.

And the moment the story began to spell out, Barriere knew he'd solved the case.

Based on the evidence collected at the crime scene and witness testimony, the following is a reconstruction of what police believe happened to Patrik Izwar on the afternoon of Monday, June 23, 2014.

At 4.30 p.m., the killer stood on a rocky hill overlooking a park and set, watching through a pair of binoculars while Patrick and Audrey walked hand-in-hand down a paved path below.

The couple was taking their time, clearly enjoying the scenery and each other's company.

And then at some point, Audrey stopped and pointed across the road at a cave in the nearby cliffs, the entrance to a cave.

And when the killer saw this, their heart began to race, and they watched intently as the couple actually crossed the road and went into the cave and vanished.

At this point, the killer lowered their binoculars and put them inside of the large duffel bag they had brought with them.

Then, after slinging this bag, they hustled down the hill and went right to the entrance of the cave.

When they reached the entrance to the cave, they stopped and they put that bag on the ground.

They unzipped it, and out of it they pulled a large rifle, a roll of duct tape, and also a white mask.

The killer put the mask on, and with the rifle and tape in hand, they entered the cave.

and they could hear the sound of Patrick and Audrey inside.

They had not gone far and they clearly had not clocked the killer coming in.

They were sort of wrapped up in their date.

However, when the killer got close enough, the couple heard their footsteps and they turned around.

When Audrey saw the killer in their mask with the gun, she began to scream.

And Patryk, he just went white as a ghost.
