Growing up , DeLong stated that her father had told her to choose a practical career . Before entering the field of criminal profiling , DeLong worked as a psychiatric nurse at Northwestern University Hospital in Chicago , Illinois . However , by the time she was 28 years old , she was a divorcee with a young son . Wanting a new career , DeLong went to Quantico , Virginia in 1980 to attend the FBI training academy . She was one of only seven female recruits . DeLong worked in the FBI 's Chicago office after graduating from Quantico . DeLong stated that she used humor to ease tensions while working . She claimed that her three career goals were as follows : " to be involved with a high-profile national criminal , I wanted to apprehend a serial killer , and I wanted to rescue a kidnap victim alive . " In 1982 , DeLong became involved in the investigation of the Chicago Tylenol murders , in which seven people died from potassium cyanide-laced Tylenol capsules . Although no one was ever charged in the poisonings , the incident led to new packaging for over-the-counter medication and federal anti-tampering laws . Regarding the incident , DeLong stated that " You can thank the Tylenol killer for the fact that it now takes a blow torch to get into a bottle of Tylenol . " In 1995 , DeLong was one of the three handpicked FBI agents to mastermind the manhunt for the Unabomber , Ted Kaczynski . Kaczynski had sent 16 bombs over a 17-year period to target areas , killing three people . After his 1995 capture in Lincoln , Montana , DeLong wrote that " he only cared about two things — his little quarter-acre of property and killing people . " DeLong , a member of the Child Abduction Task Force in San Francisco , California , stated that the greatest day of her career was when she was able to rescue a nine-year-old kidnapping victim who had been given crack cocaine and been forced to participate in child pornography .
