A Baltimore jury on Wednesday convicted Elliot Knox in the fatal shootings of Baltimore Police Officer Keona Holley and 27-year-old Justin Johnson in December 2021.

Knox, 34, faces life in prison at sentencing in June, with prosecutors previously having given notice of their intent to pursue a penalty of life imprisonment without the possibility of parole, the Baltimore Sun reports.

Officer Keona Holley was ambushed around 1:30 a.m. on Dec. 16, 2021, while sitting in her patrol car during an overtime shift in Baltimore’s Curtis Bay neighborhood.

At trial, the prosecution played video from the body camera of the first officer to find her wounded, showing his and a civilian’s harrowing effort to keep her alive. Holley had been shot in the head twice, with bullets damaging her brain and neck. The 39-year-old mother of four died in the hospital about a week after the shooting.

Travon Shaw, 34, also was charged with first-degree murder , conspiracy to commit murder and firearms offenses in both killings. A jury in October convicted him of all counts related to Johnson’s death. Shaw faces life in prison at sentencing later this month, when he is also due to stand trial on the charges stemming from Officer’s Holley’s murder.
