Phone number "Hot Sheet" ideas?
I am looking for a cost effective time efficient way to build a "hot sheet" of common contact numbers used by narcotics suspects.
Basically I download a lot of low level dealer phones and we have a ton of data but other than old fashion comparison i have not found a quick way to identify common contacts between them. I have messed around with spreadsheet pivot tables and that is as far as I have taken it. We are want to find "the big guy" hopefully by comparing all the low and mid level contacts we can locate a common source or two. Our area like many of you i am sure, has been hit by a lot of overdose deaths.
Wondering if any of you guys had any ideas or knew of a reasonable priced software that could help out.
Thanks in advance, B. Styers
