the pathologists' psychological profiling (!)
This concept is an interesting but dated one.
It really started on TV with Jack Klugman as Quincy M.E. in the 70's and 80's (Q not only uncovered the cause and motive, but also caught the killer) and has been given a new lease of life with advanced computer techniques.
All spy and crime dramas now have a computer geek/expert at their core; this has the advantage of providing a variety of new leads - on demand, and with no filming costs. A message on a screen - points the episode in whatever direction is desired.
Star Trek used a similar ploy/ruse when the 'beam me up scottie' method was used to instantly transport characters from one scene/world to the next!
