Convicted drug trafficker charged in 2001 murder

October 18, 2012 (CHICAGO)

Authorities used DNA testing to tie Adalberto Santiago to a deadly home invasion.

Santiago was sentenced for a drug case in 2009. His DNA profile was then entered into a national registry and linked to the murder of a 41- year- old man 11 years ago.

Santiago denied knowing anything about the crime, but his DNA matched blood found in the home on a knife.
