Since the Home Invasion Unit was mentioned (much of that information redacted) in the docs, some background on that may help. Here is some information from a Reuter's article from 2009 -- interestingly, dated exactly 3 years before Isabel's "disappearance."
BEGIN EXCERPT:
The desert city is less than two hour's drive from the Mexico border. It lies on a crossroads for the multimillion dollar trade in drugs headed north to market across the United States from Mexico, as well as guns and hot money proceeds headed south to the cartels.
Five years ago, police say home invasions were virtually unheard of in Tucson. Now the crimes run at three to four a week, as criminals go after the profits of the illicit trade in marijuana, black-tar heroin, cocaine and methamphetamine through the city.
"We've always dealt with those in business establishments, banks and convenience stores, it was very unusual to see them in houses," Roberto A. Villasenor, Tucson's assistant chief of police said of the recent trend. "The home was seen as a safe spot."
CAUGHT UP
Curbing drug violence is a top concern for the government in Mexico, where rival cartels murdered 6,300 people last year as they battled the authorities and each other for control of lucrative smuggling corridors to the United States.
It is also high on the U.S. agenda as authorities seek to stop cartel-related crimes such as kidnappings, home invasions and gangland-style slayings from bleeding over the porous U.S. border and taking hold here.
A year ago, Tucson police department set up a special unit to target the rising number of home invasions. Since then, the officers have investigated at least 173 cases scattered across the city, three-quarters of them tied to the drug trade, investigators say.
