Two residents who live at or near 8619 Key North Way testified Oct. 10, 2022, in the 187th District Court that they heard multiple gunshots the morning of Oct. 10 and that one witness saw a man point a handgun toward a vehicle as it drove away. The court also admitted 911 dispatch recordings after the county digital-evidence technician authenticated the files.

Jairus Siede White, who testified he was 16 at the time of the incident, said he was upstairs when he heard three shots. "I heard gunshots, and I looked out the window, and I saw them in the middle of the street," White testified. He identified the defendant, Dominic Nicholson, in court and said Nicholson was standing in the street with his arm extended pointing a black handgun toward a vehicle; White said the vehicle then drove off. White described running downstairs and briefly speaking with Nicholson at the house after the shots; he testified he did not see anyone else outside at that moment.

Deborah Concepcion, who testified through an interpreter, said she was in her living room and "heard shots." She told the court she saw a car speeding away after the shots and then called her husband and 911. Concepcion identified the 911 incident detail report and acknowledged she had listened to the recording in advance of court. The county's digital evidence technician, Denise Alvarado, testified that 911 calls and dispatch audio are stored in a database called MediaWorks and that she had located and reviewed the recording tied to BCSO case number 2022-021094. "They're kept in a database called MediaWorks," Alvarado said. When asked whether the recordings were an accurate representation of the calls, she answered, "Yes."

The state offered recorded dispatch files as exhibits. The court admitted at least one bundle of 911 recordings (identified on the record as State's Exhibit 3435) after foundation testimony from the technician; other recordings (logged as Exhibits 34, 35 and 36 during identification) were discussed on the record and the defense requested time for redactions and review for some items. The court also permitted the state to publish the admitted audio to the jury during proceedings.

Both eyewitnesses were held subject to recall by the state and the court reiterated the sequestration rule — witnesses were admonished not to discuss testimony outside the courtroom. The testimony of the two residents and the authenticated dispatch recordings formed part of the record that the jury will consider as the trial proceeds.
