Newly released documents are shedding more light as to how human remains ended up in a burn pile at a rural Evansville home. According to information in a search warrant, Nathan C. Middleton admitted burning the body of Aprina Paul after posting an ad for sex on Craigslist. The documents report on the morning of October 27, Middleton dropped off his fiancee at work and picked up Paul. The two drove to his residence at 12016 West Highway 14, where Paul "consumed an unknown type of drug". The document states Middleton admitted to having sex with the woman, but the next day he found her,"still in his bed, but she was not breathing and did not have a pulse". The document states he hid the body, and the next day put the body in the fire pit. The document does not make clear whether Middleton's fiancee knew about Paul. Middleton is in the Rock County Jail.
