After about an hour of deliberation this evening, a Montgomery County jury found Brittany Norwood, the woman accused of brutally murdering her Lululemon Athletica coworker Jayna Murray, guilty of first-degree murder.

Norwood’s attorney, Douglas Wood, had attempted to argue that she did not premeditate Murray’s murder. But graphic images from the crime scene, an account of the shocking brutality of the crime from the county medical examiner, and especially the testimony of neighboring workers at the Apple Store who heard the murder but did nothing, swayed the jury to rule otherwise.

Upon sentencing, Norwood is likely to face life in prison without parole.
