The man responsible for killing two mothers and their daughters in Prince George’s County, Md., near Washington, D.C., is a crafty serial killer who pored through books about forensic science to learn how to clean up his crime scenes and intentionally changed his killing methods to confuse detectives, the Washington Post reports. He holds two master’s degrees and was so good that he duped an FBI profiler into concluding that the killings were unrelated. Prince George’s Police Chief Roberto Hylton predicted he will be remembered as “one of America’s most infamous killers.”
The man, 27, is being held on federal weapons and sex charges, has not been charged with the killings. Officials declined to name him because he has not been charged. Hylton expects the man to be indicted within a month in connection with the killings of Delores Dewitt, 42, and her 20-year-old daughter, Ebony. Their bodies were found March 16, 2009, in a burning car that had been stolen that day.
