Rosa Hernandez

Rosa Hernandez (age: late 30s) is a police detective in Devils Lake, wife of Ángel Hernandez and mother of Karina and Jose Hernandez.

Personality
Rosa is known for being obsessively organized and by the book. She tends to annoy her coworkers with her insistence on following the letter of the law, though all hold her in high regard. This fixation on order and cleanliness creates tension in her family life, where it manifests as a tendency to micromanage Karina's life in a way that Karina resents. Ángel helps to curb the detrimental aspects of this, leading to more negative manifestations of her perfectionism and increased conflict between Rosa and Karina after Ángel's death.

Biography
Ángel and Rosa met on the job in El Paso, Texas prior to the events of the series. In a conversation with police officer Richard Hooper, Rosa explains that she and Ángel moved to Devils Lake because her supervisor in Texas was refusing to promote her to detective. Rosa is unhappy about living in such a small town and worries that Ángel resents being forced to move to help her career, despite Ángel's statements to the contrary.

Sunset Murder Investigation
In season 2, Rosa is able to identify a trend in some of the bodies that have been found in Creel Bay, identifying them as residents of the Sunset Trailer Park and tying them to a single murderer. Rosa's inability to catch the murderer is a point of frustration for her, particularly after he narrowly escapes her in a high speed chase.
