Hypothesis The most probable area for
homicide to occur in 2011 in District 6
Based on past crime reports it is a far a assumption that Districts 5, 6, & 7 will remain to have higher homicides rates
Hypothesis
District 6 recently has become the district with the most homicides.
Reasons Higher income families are moving south and
west of city
Current prevention efforts are inadequate in these areas and need to be stepped up to improve the safety of their citizens
Homicide occurrence according to stltoday between Jan. 4 and Feb. 17
Homicides have been accruing in areas predicted by the research
Homicides in the St. Louis area this year
