10 / Known witnesses & testimony status
Documented appearances: The six witnesses in the October 29 log above have been reported as testifying. Their roles are recorded there to avoid confusing an appearance with an anticipated witness.
View More Who is expected to testify next?
Court TV reports that defense counsel said Ouellette plans to testify. That stated intention is not testimony and could change. A complete authenticated prospective witness list has not been obtained. No unnamed witnesses are presented as confirmed. Sources: S06

11 / Verdicts, sentencing & appeals
As of October 29, 2026: Trial underway; no verdict or sentence is reported in the reviewed coverage. No post-verdict appeal is identified in those sources. Sources: S07
View More Outcome tracking
This section will distinguish a verdict, sentencing order, post-trial motion and appellate ruling when a reliable source establishes each development. The separate civil lawsuit is tracked independently. Sources: S12

12 / Unresolved questions
View More How did Sophie leave the truck, and how were the fatal injuries inflicted?
The parties offer competing accounts. The trial’s evidence must be evaluated without assuming that either account has already been proven. Sources: S06
View More What can the location data reliably establish?
View More Which original records remain unavailable in this file?
A certified trial transcript, authenticated full witness list, complete exhibit index and original digital files have not been obtained. Those gaps prevent independent reconstruction of every event; they are not evidence that an item does not exist.
