GREENSBURG (KDKA) -- Testimony continues today in the penalty phase for one of members of the so-called "Greensburg 6" in Westmoreland County.
Jurors today heard testimony about the injuries sustained by the victim, 30-year-old Jennifer Daugherty.
Melvin Knight is on trial in connection with Daugherty's torture and death.
Dr. Cyril Wecht told jurors that Daugherty suffered injuries all over her body, but died as a result of seven stab wounds some of which punctured her heart and lung.
Wecht says Daugherty probably lived four to six minutes after the fatal stab wounds were inflicted, but only one to two minutes would have been conscious life.
Still, he said she suffered a painful death because she likely lived with other injuries for quite some time.
Knight could be sentenced to death in the penalty phase of his trial. He pleaded guilty to the torture and murder of Daugherty.
Co-defendant Amber Meidinger sobbed as she left the courtroom, stopping and turning to Jennifer Daugherty's family saying, "I'm sorry. I'm so sorry."
On the stand, Meidinger admitted that she had lied to investigators during three initial interviews, but later contacted the district attorney's office from prison saying she wanted to cooperate and testify against her co-defendants, including the father of her child.
She said, "I figured I would want to tell them and the family the truth about what happened. It's horrible what happened."
