Law & Order: Season 13, Episode 3

13 - 3: True Crime

Investigating the death of a rock band singer who had large amounts of cocaine and heroin in her system, the detectives question a former boyfriend who was a disgruntled band mate of her late husband. The prosecutors are hampered by the actions of a retired detective-turned-writer, who worked a case with Briscoe several years back and whose unconventional research tactics make him a suspect as well.
