The red and white chequered blanket from the bomb car was examined by Bob Barnes at the Materials Research Laboratory. The blanket didn't belong to the owner of the stolen bomb car so it must have been put there by the bombers. The rug was in remarkably good condition considering that Barnes concluded it had been used to cover the timing device of the bomb. Barnes examined the blanket for explosives residue and in the process, found some short dog hairs from a terrier-type dog. He passed his findings on to detectives from the Taskforce.
