Law & Order S16E05 - Life Line

When the body of undercover reporter Teresa Richter is discovered, police soon realize her death is connected to the story she was working on about a Latin gang, L-12. Their investigation leads them to Kevin Drucker, a businessman who reported his car stolen but who was really paying off members of L-12 not to hurt his son Patterson, who was imprisoned on the same cell block with many of the gang members. McCoy and Borgia realize that the only way they can get to L-12, who ordered the hit on Richter, is to get Drucker to testify. Drucker is reluctant to do so, however, unless his son's safety can be guaranteed.
