For the jurors deciding Brittany Norwood’s fate, some of the most gruesome testimony about the March attack that left 30-year-old Jayna Murray dead lies ahead. The jury has already seen the bloodied rope found around Murray’s neck at the Lululemon Athletica where she was killed in a brutal fight with Norwood, her co-worker, in March. The jury has seen photographs of the Bethesda store’s white floors turned red by blood. Jurors have viewed full-body photographs of Murray’s slain body, and heard from the man who found her dead in the store.

But the testimony at Norwood’s first-degree murder trial is expected to become even more grisly this week, when a medical examiner is slated to testify about the hundreds of injuries Murray suffered.
