In this episode, Lydia and Russell are told that they will not be able to get a rape kit analyzed (and possibly find out who the rapist is) because there is such a large backlog of forensic materials in the lab waiting to be analyzed that some of the waiting cases are over ten years old. This is taken straight from a true scandal of Los Angeles law enforcement: in March 2009, the organization Human Rights Watch released a report revealing that at that time, there was a backlog of over 12,600 untested rape kits in storage facilities; over 450 of those were over 10 years old; and many of those were evidence in cases for which the statute of limitations had expired.
Although they play father and daughter on the show, Kevin Alejandro (Detective Nate Moretta) and Alyssa Diaz (Mercedes Moretta) are only 9 years apart.
At about four minutes in, when an officer is talking about types of rope, the Watts Towers appear in the background of the scene.
