aged 5 and 7, lived with their parents, Reinhard and Monika, in Germany. They were reported missing on 4 August 1986. Their bodies were found on 7 August. They had been murdered. Monika first said the children had breakfast, then went to a playground. Three weeks later she said they were already dead when she returned home the previous night: Reinhard was sitting on the edge of Karola's bed, weeping and confused; he then disposed of the bodies. Both parents were suspected, but Monika was having an affair, and was seen where Melanie's body was later found. She was convicted, and after serving her sentence, was released in 2006. Investigators determined what clothes Monika was wearing on 3 and 4 August, but not Reinhard's clothes, so only fibres from her clothing were identified on the children's bodies, yet they were also constantly in contact with him. The bedding contained 14 fibres from Karola's T-shirt. Frictionless tests, simulating a dead child, matched that figure better than the friction tests, simulating a live child, so Karola could have lain lifelessly in bed wearing her T-shirt, as stated by her mother. 35 fibres from Monika's blouse were found on the back of Melanie's T-shirt, but only one on her bed sheet. In tests, between 6 and 10 fibres remained on the sheet. These higher numbers were thought to disprove Monika's claim that she gave her child a goodbye hug the previous day. However, there are several likely explanations. For example, the bedding was put in one bag, so fibres from the sheet could have been transferred to the cover and pillow. Only the central area of the top of the sheet was taped: it might have originally contained more than one blouse fibre, the others could have been transferred to the back or sides while in the bag. The blouse fibres on Melanie's clothing were distributed evenly, not the clusters expected from carrying the body. 265 fibres from the family car's rear seat covers were found on Melanie's panties and the inside of her trousers, but only a small number of fibres from the front seats was found on the children. This helped disprove the theory that they were killed on the front seats. Melanie's clothes and hair were covered in 375 clinging fruits of goosegrass. As some of these itchy things were on the inside of her trousers and on her panties,
