Texas Man Charged with Murder of Coworker Over Alleged Obsession

Travis Merrill, 51, reportedly killed his coworker Tamhara Collazo after becoming fixated on her work breaks and lack of attention toward him.

Travis Merrill was arrested for the fatal shooting of his coworker, Tamhara Collazo, at their workplace in Lewisville, Texas.
Merrill allegedly developed an obsession with Collazo, tracking her work breaks and growing angry over her perceived inattention.
Collazo had reported Merrill's concerning behavior to human resources, leading to his temporary suspension and requirement to seek counseling.
After returning to work, Merrill reportedly purchased firearms and planned the attack, which he carried out at Collazo's desk.
Allegiance Trucks, the employer, has closed its Lewisville office indefinitely and is cooperating with law enforcement in the investigation.
