Is accused murderer Brittany Norwood merely a woman who lost control or is she a master manipulator?

That's the question before the jury who will decide the fate of Norwood, who is accused of killing her co-worker Jayna Murray at the Lululemon yoga store in Bethesda.

During closing arguments Wednesday, prosecutor John McCarthy said that all the forensic evidence proves that Norwood committed a premeditated murder.

“Could you begin to even count the number of times she lied?” asked prosecutor John McCarthy during closing statements. "It’s almost impossible.”

McCarthy said Norwood staged the entire crime scene and altered every room of the Lululemon store.

“She had 10 hours to make this scene look the way she wanted,’ he said.

The jury began deliberating Wednesday night.

Testimony from the medical examiner who conducted Murray's autopsy, during which the controversial photos were shown, was preceded by several members of her family leaving the courtroom.

While on the stand, Dr. Mary Ripple said that Murray suffered 322 separate injuries to her body, mostly to her head.

This testimony from Dr. Ripple comes a day after a forensic technician testified that "something seemed odd" at the bloody Lululemon crime scene he was sent to investigate in March.

The technician also told the jury how it was possible for Norwood to bind herself with zip ties, at one point getting up to demonstrate how to do it by using his teeth.

On the night of the murder, Norwood was found bound and bloodied in the back of the yoga clothing store.

Prosecutors believe all of the witness testimony will help seal the deal on first degree murder charges in the case against Norwood.

Jurors also saw a two hour police interview with Norwood just two days before her arrest. During the interview, Norwood claimed to have stepped in Murray's blood in the wake of the attack, but her story quickly began to unravel.

Detective Jim Drewry said he initially considered Norwood a victim based on her account that two men had attacked her and coworker Jayna Murray.

But police said Norwood became a suspect after her story started to unravel. She was arrested a short time later.
