Multiple witnesses, including a forensic data analyst, testified before a jury in DC Superior Court Judge Jason Park’s courtroom on March 10.

Nyjell Outler, 22, is charged with first-degree murder premeditated while armed, assault with intent to kill while armed, aggravated assault knowingly while armed, assault with a dangerous weapon, and four counts of possession of a firearm during a crime of violence, for his alleged involvement in the murder of Demetris Johnson, 21, on March 20, 2021 on the unit block of Madison Street, NE at a gender reveal party. The incident also left another victim injured in both legs. All charges face an aggravating factor of allegedly being committed during Outler’s release in another matter.

The forensic analyst testified that DNA testing on a backpack and drum magazine found at the scene indicated Outler was more than likely a contributor among four individuals detected.

The prosecution also called on a medical examiner who conducted Johnson’s autopsy report. The witness confirmed that the cause of death was a gunshot wound to the back, and the manner of death a homicide.

Outler’s Pretrial Services Agency (PSA) officer, who ensured he was compliant with release conditions in his other case, told the jury that he was alerted of a GPS monitor strap tamper on the night of the incident, along with multiple critical battery alerts. The witness stated he spoke to Outler weekly, and attempted to reach him through contacting his mother and girlfriend that night but was unable to.

An expert witness called on by the prosecution also confirmed that Outler’s GPS location was pinged on Madison Street, NE and North Capitol Street at the time of the shooting, allegedly placing him at the scene.

Parties are slated to reconvene March 11.
