I suggest you start with the library research guide on criminal justice
http://library.uhd.edu/cj?hs=a. To find the guide yourself, start at the
library homepage http://www.uhd.edu/library/ and go to the dark gray RESEARCH
GUIDES tab. Click on the link for Criminal Justice. Then click the first
link on the following page "Criminal Justice."

Once in the Criminal Justice Research Guide, take a look at the Databases listed in the middle of the screen. I suggest you
start with "SAGE Journals Online" or "Taylor & Francis Online." All of
the articles in both of these databases are from peer-reviewed journals.

Here are some suggested search terms to try in each of the databases:
drug trafficking
drug war 
drug cartels

Add some of these terms to narrow down the geographic location:
Mexico
Mexican
Texas
United States border
