Who Killed Cordell Walker's Wife on 'Walker'? The Mystery Has Been Solved (SPOILERS)

In the series premiere of Walker, Cordell and his family are fractured as they confront their unresolved grief with the death of his wife, Emily (Genevieve Padalecki). The episode jumps ahead to 10 months after Emily was murdered when the Texas Ranger returns home from an undercover mission. Walker is still obsessed with his wife's death, and we see him constantly flipping a poker chip that she had on her the night of her death.  

He can't figure out what the chip has to do with his wife but makes it his mission to find its connection and solve the mystery of Emily's untimely death. In Episode 6 of the CW drama, Cordell's brother Liam (Keegan Allen) teams up with Captain Larry James (Coby Bell) to investigate a lead about her murder in Mexico. 

Somehow, Emily's best friend Geri (Odette Annable) may be connected to the murder. In Episode 7 of Walker, the pair head down to Mexico to an art gallery that Geri's LLP money is going to.

Interestingly the woman who runs the gallery is the niece of the man who confessed to Emily's murder. It seems like Captain James and Liam must be on to something because right as the episode is ending, viewers see them walking to their car to leave Mexico, and as James hits the automatic lock for the car, it explodes! However, by the next episode, even more of the story is finally put into context.

So, who killed Walker's wife? Read further to learn all the details.

Although the situation with the car-bombing and the woman who runs the gallery proved to be promising, the biggest lead into what happened to Emily comes when Walker finds out that her best friend, Geri Broussard, worked for the Northside Nation. Upon confronting her, Geri offers to wear a wire at a Northside Nation meeting in order to gather information for the upcoming bust.

When Walker and the Rangers have enough information to do the bust (albeit on different charges than originally planned) a woman named Cali flees the scene. At that moment, she reveals that she was the one who actually murdered Emily. 

Cali was working on transporting drugs across the border at the same time Emily was doing humanitarian work, and being in the wrong place at the wrong time led to her tragic death at Cali's hands.

The situation continues to develop into a chase, with Cali actually getting her hands on Walker at one point and fully poising herself to kill him. Luckily, Geri appears once again at the last second and manages to shoot Cali dead, saving Walker and avenging her late best friend.

Since Walker began, its existence has relied on two identity crises' for Walker himself: the fact that his wife was murdered and the fact that he took a months-long undercover mission directly after that at a vulnerable time for his family. 

Of course, fans of the show know Walker was able to reconcile with his family fairly quickly in the first half of the season, but now that Emily's killer has been found it seems like the two biggest story arcs from the beginning have been resolved.
