TEEX also has new cheap online forensics/law enforcement courses

[Ideas]

Basic Criminal Investigation (Online)
FSA113
$75
In the lower-division baccalaureate/associate degree category, 2 semester hours in criminal investigation or criminal justice

Death Investigation (Online)
FSA114 
$75
In the upper-division baccalaureate degree category, 3 semester hours in criminal justice, criminal investigation, or forensics

These two say:

Price shown is for commissioned Texas peace officers or non-commissioned personnel employed by a Texas law enforcement agency. Additional fees will apply for out of state and others.

and:

Course Completion Requirements

• Must be licensed or certified peace officer with a current commission or non-commissioned personnel assigned to investigate/process crime scenes
  

They also say 40.0 hours instead of 16.0 hours.

Probably still cheap without the discount.
