Brooke Skylar Richardson, 20, was not found guilty of serious murder, involuntary manslaughter, and the endangerment of children.
When the verdicts were read on Thursday, Richardson sobbed before being handcuffed out of the courtroom.
Richardson brought her baby on the evening of 7. May 2017, when she was 18, home to the world.
Two months after the birth of the baby named Annabelle Investigators found the remains of the skeleton in a shallow grave with a flower set by Richardson.
The sheriff's office initiated an investigation leading to the remains after she showed up in the doctor's office without a baby ̵
The prosecutor said when the doctor asked her, she burst into tears and said the baby was not alive at birth and she had her buried in the backyard.
Prosecutors painted a picture of a teenager who was in a new relationship at the time and did not want to have anything to do with the baby or the man who impregnated her. They claimed that she had killed the baby after she had been born in the middle of the night because she thought she had no future as a mother.
"When Brooke Richardson found out she was pregnant by a boy with whom she had nothing to do, she burst into tears and told her doctor that she could not get this baby," Prosecutor Steve Knippen told the jury affiliate this month.
The prosecution showed the court a picture of her in the gym hours after giving birth and said she sent a message to her mother.
"My belly is back, OMG, I'll never, never, never look like that again, you'll see how I look better than before, OMG," the text message said.
But her defense team said there was no evidence that the baby was born alive. Richardson said Annabelle did not move or breath at birth, her defense team said.
"She buried her daughter and marked the tomb with flowers on it, she did not throw her in a trash can, she did not throw her in a dumpster," said defender Charlie Rittgers affiliate. "She has been living under this dark cloud for the past two years, to be honest, a nightmare."
Richardson did not comment on her own defense.
