Alton Private Investigator

The State of Illinois boasts a population of nearly 13 million people, but its crime rates are on par with the national averages in terms of violent and property crimes, or “index crimes.”  In 2011, 401,272 index crimes were reported, which calculates to 31.18 per 1,000 residents.  Of those, 4.29 were violent compared to 26.89 property crimes, both of which are similar to the national medians of 3.9 and 29.1, respectively.  Alton accounts for only 28,000 residents, but its crime rates are substantially higher than the State averages.  Violent crimes were reported at 5.44 per 1,000 residents, and property crimes were at 50.00.  In such a concentrated area, it is common for crime rates to spike, but that does not reduce the need for additional resources for crime prevention and investigation.  Private investigators, such as those licensed by ICS, may be a necessary supplement to the efforts of local law enforcement.  By employing one, you are ensuring that a highly skilled, experienced professional is dedicated to working your case around the clock.
