Reason to be afraid -- over 50 unsolved cases of serial murderFact: murderers and serial killers do not always get caught. Behind every headline of a newsworthy conviction lie other cases of vicious murderers who got away, and who remain somewhere among us. Here in one giant volume are more than 50 of the most serious serial killings and other murder cases that continue to remain unsolved. The cases covered in this alarming book include: " Argentina's crazed highway killer, responsible for mutilating and killing at least five people since 1997, and dumping their bodies along remote highways " The Green River Killer, believed to be a middle-aged white man, who has claimed at least 49 lives to date in the Seattle-Tacoma area " South Africa's 'Phoenix Strangler', suspected of killing 20 women in the province of KwaZulu Natal. " The Twin Cities Killer -- either one or several people responsible for a series of over 30 murders on the streets of Minneapolis and St. Paul, where the victims were mostly prostitutes " Costa Rica's elusive 'El Psicopata' (The Psychopath), thought to have murdered at least 19 people in this small quiet Central American country " 'The Monster of Florence', responsible for a series of 15 sexual slayings just outside Florence In each case it is not just the crimes that are horrifying and fascinating, but the response of local police and authorities to the lack of a conviction. Local authorities may fear to admit the continued existence of a serial killer at large; whilst police bodies face the temptation to 'tidy up' loose unsolved murders under the aegis of other admitted crimes.
