CHICAGO (CBS) — A researcher has found a significant connection between shootings on the South and West Sides and the locations of liquor stores.

Police and neighborhood activists have long said that liquor stores are a breeding ground for crime and gangs, attracting criminals who tend to loiter outside.

Now a researcher as taken a look at crime data and the locations of liquor stores to determine just how much violent crime is linked to those locations.

Northwestern University Medical Center trauma surgeon Marie Crandall looked at census and liquor store locations and shooting victim data over a 10-year period.

She found that people in certain communities are 500 times more likely to be shot if they are near a liquor store than any other part of the community.

Crandall said the study could open up discussions about the availability of alcohol in city neighborhoods already suffering from poverty, crime and a lack of access to good, healthy food.
