A grandmother has been jailed for 20 years for her role in the harrowing, multi family-member abuse of her 16-year-old adopted granddaughter which led to her death.

Sabrina Ray died in May 2017 at her home in Perry, Iowa. She weighed just 56lbs when she died despite being 16-years-old.

Sabrina's adoptive parents Marc and Misty had starved her egregiously and her brother had beaten her.

On the day of her death, she was at her grandmother Carla Bousman's home witht two other adopted girls.

Marc and Misty were on their way to Florida for a two-week vacation to Disney World for one of their biological sons birthdays.

Despite seeing Sabrina vomit and soil herself on the morning of May 12, Carla, 63, locked her in a room with the two other girls and did not seek medical help.

Carla Bousman, 63, was jailed for 20 years on Friday for her neglect of 16-year-old Sabrina Ray (left), her adoptive granddaughter who died in May 2017 as a result of egregious malnutrition caused by the family which took her in

The teenager died later that day as a cause of malnutrition caused by deprivation of food.

On Friday, Bousman wept as she was jailed for 20 years for neglect. She pleaded guilty earlier this year.

'I wish I could go back to that day and change everything and do what I know was the proper thing to do.

'I can’t change what was done now, but I’m very sorry and miss all my grandchildren very much,' Bousman said, according to The Des Moines Register.

Prosecutors said that while she did not starve and beat the girl herself, her lack of action on the day of Sabrina's death led to it.

During her court appearances, Bousman described the teenager's condition in her final day.

'She had woke up vomiting and had soiled herself and her clothes and I just thought that she wasn’t feeling well and I gave her a shower and cleaned her all up,' she said.

Sabrina had gone to live with the family in 2011 after being taken into the care of authorities away from her methamphetamine-addict father.

The Bousmans first took her in as a foster child but adopted her in 2013. She was homeschooled.

Three other children were removed from the home after Sabrina's death.

Josie Bousman, one of Misty and Marc's nieces, was also charged with lying to police to cover up how she was abused.
