The First 48

The Chase/One Shot (11x15)

: 20, 2011

In Harris County, Deputy Abraham Alanis is working the homicide of a 69-year-old Navy veteran. When Alanis' first big break, surveillance video of the potential perpetrator, fails to show the suspect's face, investigators take a closer at the footage and notice something big--a small detail in the video, could be a huge break for the case. And in Birmingham, Det. Marcel Walker responds to the city's first homicide since a deadly tornado ravaged the city. Walker needs to determine whether two people seen fleeing the crime scene moments after the shooting are witnesses to the heinous act or responsible for it.
