After taking a cocktail of pills that left her sedated, Somers said her mother told her she no longer wanted MacNeill to dispense her medication since she couldn't see through the bandages on her face.
"She actually had me take out every single pill from the pill bottles and she wanted to feel what the pills feel like in her fingers, so if my dad tried to give her anything, she would know what he was giving her," Somers said.
On April 10, 2007, Somers said she left her family's home in Pleasant Grove, Utah, to go back to medical school in Henderson, Nev.
Somers told the court her mother "was feeling really well" when she left.
The next day, the mother of eight was found by her 6-year-old daughter unconscious in a bathtub full of brown water. Less than two hours later, Michele MacNeill was dead.
The trial, which is in its fourth of five scheduled weeks, has played out like a soap opera in the court room.
Willis, the woman who prosecutors allege was MacNeill's motive for murder, testified that she moved into the family's home days after Michele MacNeill's death and that she was hired to work as a nanny.
Four of MacNeill's daughters told the jury in Provo, Utah, that Willis never looked after the children, and instead was "goo eyes" at their father, who months later, proposed to her with a four-and-a-half carat diamond ring.
