A Lincoln couple will spend two to three years in prison for abusing their young son while at Children’s Hospital in Omaha. Benjamin and Joanna Langston were caught by surveillance cameras disconnecting their son’s feeding tube. The child was diagnosed with failure to thrive and was put on a feeding tube. The child’s condition continued to deteriorate. The hospital then installed a security camera which videotaped the couple removing the tube so Joanna Langston could breast feed the baby. The Langston’s will have to spend at least one year in prison. Their four children are in foster care.
