The second round of searches provided a relevant article that reiterates the initial information but does not add substantial new details. It confirms the victim's name as 44-year-old Vernon Plummer, the suspect as 32-year-old Nicole Jordan of Poteau, the date of the incident as Friday, March 22, 2019, and the location as a residence southeast of Sallisaw.
It also reconfirms that Jordan was booked into the Sequoyah County jail on a charge of second-degree murder and that the OSBI took over the investigation.
However, there is no new information about the circumstances of the shooting, the relationship between Plummer and Jordan, or the outcome of the legal proceedings against Nicole Jordan. To provide a more detailed synopsis that reads like a story, I need to find information on these aspects.
Therefore, I will execute a new set of search queries focused on finding updates on the case, including the results of the OSBI investigation and the court proceedings for Nicole Jordan.
