Ep 5. What + Why = Who

In Making a Murderer season 2 episode 5, entitled "What + Why = Who," the focus shifts to the investigation of the murder of Teresa Halbach and the methods used by law enforcement to build a case against Steven Avery and Brendan Dassey.

The episode delves into the different pieces of evidence presented at trial, including the DNA found on the hood latch of Halbach's car, which the prosecution argued linked Avery to the crime scene. The defense, however, disputed the reliability of the testing methods used and called into question the validity of the evidence.

The episode also explores the motives behind the investigation and the potential biases of those involved in the case. The filmmakers examine whether the investigation and subsequent trial were conducted with the goal of uncovering the truth or building a case against Avery and Dassey.

Viewers are presented with multiple theories and potential suspects, including an ex-boyfriend of Halbach who had allegedly stalked her and a suspect who was investigated in connection with a separate case involving a similar crime.

As the episode unfolds, viewers are left to question whether the investigation and trial were truly impartial, and whether justice was truly served in the case of Teresa Halbach's murder.

Overall, "What + Why = Who" offers a nuanced exploration of the complex and controversial case, challenging viewers to consider the ways in which the justice system can fail those it aims to defend.
