As part of a series of special reports that could have come with a co-byline from Quentin Tarantino, Reuters has confirmed that it bought two human heads and part of a spine while investigating "body brokers", America's largely unregulated vendors of human parts. According to the news agency, reporter Brian Grow was able to buy the heads and the cervical spine "after just a few email exchanges". Each head, and the spine cost $US300 ($390), plus shipping, each.
