Bridge Conversation

The Bridge Conversation was a conversation that took place between Jackie Riemowski and Ross Moebus around the time of the murder. The timing of this event is disputed.

Beginning
Jackie was advancing towards the bridge when Ross crossed it as well. Seeing Jackie, he began very persistently asking for help with a geometry assignment, per some of the testing he was undergoing. This lasted for at least four to five minutes, with Ross "not leaving Jackie alone" when Jackie decided to shake him more aggressively.

Phone Call
Ross testified that when Jackie (claimed to have) received a phone call, she said she had it in vibrate. Ross cannot say with certainty whether or not he heard a buzz. However, Riemowski testified that she had in fact been lying to Ross and had merely been attempting to get him to leave her alone. In particular, the phone call was faked. She claimed that the faked phone exchange was something like "I explained that somebody was holding me up at the side of the bridge, to try and guilt him. Didn't work. Asked how things were going, if our plan was still on. Things like that?"

Smiles cannot attest to anything he may have heard, but does say that Ross appeared to be following Jackie for a bit, as seen in the second illustration done below.

Additionally, Riemowski and Moebus both describe the phone call as taking place at approximately 7:30 PM. Smiles, however, describes the phone call at taking place at approximately 6:40 PM. All other events were perceived with the same inexplicable fifty minute gap between the accounts of Riemowski and Moebus and the account of Smiles.

Termination
According to Jackie, it only ended when, after great difficulty, she persuaded Ross to simply submit the test and go for a walk to alleviate stress. Jackie attested to the exact time of submission. Evidence was later produced supporting this: the exact time of submission was 7:45.

Timing Contradiction
For an as yet unexplained reason, Johnny Smiles perceived all events pertaining to the Bridge Conversation (and, presumably, all the events of that night) as occurring fifty minutes prior to the time both Moebus and Riemowski perceived them as occurring. The time of submission of Moebus's test supports Riemowski and Moebus's version of events (~7:30 PM to ~7:45 PM), however.

Afterwards, Jackie fixed a loose rope on the bridge. According to both herself and Smiles, she did nothing else, and this took approximately one minute.

Movement Diagrams
Smiles and Jackie independently diagrammed the movements of the parties in this conversation to the court. They were identical with minor variations, consistent with the positioning of the actors. It's worth noting that Smiles likely stopped paying attention to the area of the confrontation afterwards, and his attention was grabbed by the confrontation during that time.
