AUBURN HILLS, Mich. Its hard to imagine what Rebecca and Robert Kiesseling are going through after both of their sons overdosed on the same day. I was the good parent, Rebecca Kiesseling said. They call it bricks on the street, Rebecca Kiesseling said. Rebecca Kiesseling said making the call to the boys biological mother about their death was the hardest thing shes ever had to do. She hadnt seen them in a long time and she had seen the both of them this past week, Rebecca Kiesseling said.
