The mentioned application does not seem to be Free Software.
Please do not advertise proprietäre Software on this list.

What you want basically is something that displays point data (crime locations) 
regarding their attributes (e.g. morning=green, night=blue)
over a base map (e.g. your city quarters or streets).

An advanced application would be to plot densities
for certain areas.

It can certainly be done with the tools you can find on freegis.org.
Still you would need some expertise to build the application itself
as there is no ready available system for crime analysis ready yet.

I suggest trying to find a GIS analyst/programmer which will
help you to pick a free software component he is familiar with
and hands on build the application for you.

Mapserver certainly can server base maps and point information.
You would need to add special display options and analysis functions
for your cause, too.
