Logan Echolls was Veronica's husband. Formerly Duncan Kane's best friend, he is a snarky, witty 09er who ranges from being hostile to deeply caring. He was dating Duncan's sister and Veronica's best friend, Lilly Kane , on and off for two years until she was murdered during their sophomore year, and he later finds out that the killer was his A-list actor father, Aaron Echolls.
Veronica's choices at the time leave Logan feeling betrayed and he takes to bullying her. When his mother commits suicide during his junior year, Veronica assists him in confirming her death, and they later begin dating. Logan overcomes much of his inner turmoil after becoming a Naval Intelligence Officer, and begins seeing a therapist regularly.
Eventually, after years of relationship strains, Veronica agrees to marry Logan. Described as Neptune High 's "obligatory psychotic jackass" by Veronica Pilot , Logan was originally one of the school's main bullies and a nemesis for Veronica.
But as time passed, Veronica discovered that Logan was much more than that. The abused son of superstar movie actor Aaron Echolls , Logan was the on-again, off-again boyfriend of the deceased Lilly Kane and close friends with Veronica Mars and her then-boyfriend Duncan Kane. Logan's life is torn apart when Lilly is murdered and Keith Mars publicly accuses Jake Kane , father of Lilly and Duncan, of the crime.
Logan is horrified by the accusation, and when Veronica refuses to renounce her father, Logan quickly moves to blackball Veronica from the popular "09er" crowd. Logan is the youngest child in the Echolls family. His older, adopted sister Trina left the family to pursue an acting career with little success.
