Clark County court records show Samantha Moreno-Rodriguez entered the plea agreement Sept. 1. KLAS-TV reports she will serve at least 28 years in prison for murder, child abuse, and neglect or endangerment resulting in substantial bodily harm.
Moreno-Rodriguez will reportedly be eligible for parole after 20 years.
Moreno-Rodriguez and Husted reportedly left California on May 24. She allegedly left her son's father a message saying, "I'm sorry. I had to do this."
She reportedly confessed to strangling the little boy, who was autistic, stripping him of his clothes, and leaving his body. According to KLAS, Husted reportedly suffered several injuries, and his body was found near some bushes off of a dirt road.
