A teacher who once tried to raise the alarm about the well-being of her student spoke in court Wednesday, years after the child was found dead in a washing machine at his Spring home. Troy Khoeler’s adoptive father, Jemaine Thomas, 45, was sentenced to 50 years in prison after pleading guilty to murder. His wife, Tiffany Thomas, 38, who also faced charges, pleaded guilty to injury to a child and is awaiting sentencing.
