Two Americans stole adult and infant body parts from a museum inside a Bangkok hospital and tried to ship them to Las Vegas , Thai police say . The two men , identified as Ryan Edward McPherson and Daniel Jamon Tanner , told police they wanted to surprise their friends back home , Royal Thai Police Deputy Commissioner Gen. Ruangsak Jritake said . It was not immediately clear whether McPherson or Tanner had attorneys . A delivery company intervened in the shipment . On Saturday , a DHL office in Thailand 's Pathum Thani province called police after workers there were scanning shipments and discovered the body parts inside three packages . The packages contained five acrylic plastic boxes , Jritake said . One box contained an infant 's head ; another contained a baby 's left foot , which was sliced into three pieces , the police official said . The other acrylic boxes contained an adult heart and adult skin . `` We have talked with an American who was trying to send the parcels to the USA , but we could not press any charges on him and we are not quite sure which laws we can apply to him . '' Bang Pongpang police chief Col. Adisorn Semsawat said over the weekend . At the time , police said the American told them he found the infant body parts at a night flea market and that he had paid about $ 100 for them -- though he could not remember where the market was located . But on Monday , authorities revealed more details on the case . All the body parts were stolen from the Siriraj Medical Museum within Siriraj Hospital , the largest hospital in Thailand , Jritake said . The body parts were taken from the forensic medicine museum and anatomical museum . Police said closed-circuit video from the hospital showed two men identified as McPherson and Tanner . A Thai criminal court approved arrest warrants for the two men on charges of theft from a government hospital , police said . If convicted , McPherson and Tanner could face up to seven years in prison or a fine of up to 500,000 Thai baht ( $ 15,200 ) . But the Americans have already left Thailand for Cambodia . Thai officials may have to seek the two men 's extradition . Thai police say they 've been in touch with the U.S. Embassy . Not the first time . The bizarre discovery is not the first time infant remains have been found in Thailand . In 2010 , more than 2,000 illegally aborted fetuses were recovered at a Buddhist temple in Bangkok . Infant body parts can be bought on the Thai black market . Some Thais practice black magic and believe that supernatural power comes from infant body parts , if the rites are performed by monks or sorcerers . They believe that having the items provides protection and business success and can ward off bad luck . Police say in 2010 , the smell of decay led investigators to the Phai-nguern Chotinaram temple in central Bangkok , where they discovered more than 2,000 illegally aborted fetuses . Three people were arrested , including two morticians who were charged with hiding bodies . According to the hospital museum website , for 120 years `` Siriraj Hospital has collectively gathered an enormous compilation of medical equipments and tools , anatomical and clinical specimens including important artifacts and archives relating to the history of medicine in Thailand . ''
If convicted , the two Americans could face 7 years in prison or be fined $ 15,200 . The packages included an infant 's head , a sliced foot and an adult heart .
