A jury was seated Tuesday in the Frederick trial of a 20-year-old woman accused of fatally stabbing her grandmother just before Christmas 2014.
The jury of eight women and four men was seated Tuesday for the trial of Hestina Harris, who is charged with first-degree murder in the death of her grandmother, 67-year-old Lillie Morris.
Lawyers say they also expect to make opening statements Tuesday.
On Dec. 22, 2014, Morris was found bleeding on the front lawn of the home near Burkittsville that she shared with her husband, Harris and Harris' 4-month-old daughter. Prosecutors said Morris was stabbed or cut 23 times with a kitchen knife.
She died while being rushed to a hospital.
Harris told police she saw a man in a ski mask running from the house. Investigators found blood on Harris' arms and clothing that she said came from her efforts to help her wounded grandmother.
Defense attorneys say that if Harris is convicted, they'll present evidence that mental illness makes her not criminally responsible.
