They were building the bomb days before.

They planted the bomb in advance of the bombing.

So there was a bigger window of time that they were wondering who was at Kem's house, who was acting suspicious near Kem's house in the days leading up to the bombing.

Those were the questions they had for the neighbors.

And so this officer that was running over to Shepard, that's what they had been doing, re-canvassing the neighborhood.

And when he reached Shepard, he told him he'd found something.

Shepard eagerly followed the officer over to one of Kem's neighbor's houses, and there he saw a little girl, maybe 10 or 11 years old, standing nervously next to her father.

And based on what this little girl would say, along with evidence collected by the Bloomington Police Department and the ATF, this is a reconstruction of what authorities believe happened to Kem Wenger on May 22, 1993.

At around 10.30 that morning, the killer pulled up in their car outside of Kem's house.

They picked up a bag that was sitting on their passenger seat, which contained a partially completed pipe bomb and some tools.

With this in hand, they got out of the car and they walked up to the front door and they pulled a key from their pocket.

This was the same key they had stolen from under the doormat a few months earlier.

They used the key to unlock the front door and they let themselves inside.

The killer then walked down to the basement where they took all the various items from the bag and placed them on the counter and they got to work.

The killer was not worried about getting caught.

They knew this neighborhood very well, and everybody in this neighborhood knew them, and they would not find it suspicious at all to see them there.

Plus, they knew they would have an alibi for the time period when the bomb actually would go off.

Once the bomb was mostly assembled, the killer gathered up most of their things.

They left behind some random supplies in the basement, but figured it didn't really matter since the explosion would take care of everything.

Feeling very confident in their workmanship so far, the killer walked back upstairs and placed the nearly completed bomb on the floor in the foyer.
