More testimony is scheduled today in the trial of the parents accused of second-degree murder in the death of their son. Prosecutors claim Stanley and Colleen Rimer neglected four-year-old Jason Rimer, who died after being left in the family’s SUV for at least 17 hours in 2008. On the witness stand Thursday was one of the Rimer’s other children. Crystal Davis testified that Jason and his siblings lived in unsafe and unsanitary conditions. She said he was mostly responsible for Jason, who suffered from a muscular disorder. Davis also claimed Stanley Rimer would use a boat oar, paint stirrers and his fists to strike the children. Prosecutors claim the parents were involved in a pattern of neglect. Defense attorneys contend the parents were fighting their own illnesses on the day Jason was left in the SUV, and that their boys were told to take care of Jason.
