UPDATE: I definitely can’t stand by the statistic I quoted in this post; it’s way too high, it seems. See the discussion in the comments for details.
Original post follows.
From an article about serial killers who work as truck drivers:
In early 2009, the FBI announced the Highway Serial Killings Initiative, focused on killers who choose their victims and dump their bodies along highways. Some of the victims are hitchhikers and stranded motorists, but most are truck stop prostitutes. In the 1980s, the FBI was accused of inflating the numbers of serial homicides, fomenting a serial killer “panic,” so they are careful not to overstate their case today. But recent studies suggest that the numbers of serial murder victims have continually been underestimated—even during the serial murder “panic.” The undercounting is because the vast majority of victims have always been prostitutes—as many as 75% according to one scholar. Research into prostitute mortality suggests that the homicide rate for prostitutes is 229 out of every 100,000. The U.S. national average is five.
