And maybe he saw her to do list and thought to make it look like Suzanne was washing the sheets since the girls were due home on Mother’s Day and he wanted to make it look like she was abducted on a bike ride that day. Or maybe Suzanne did wash the sheets herself and put them in the dryer on Saturday. Then Barry ran a load to get rid of evidence, took the sheets out of the dryer to dry his clothes and then put the sheets back in the dryer when he was finished. He might not have had time to make the bed and wouldn’t want his DNA on the sheets. He probably doesn’t know how to make a bed properly anyway!
