Josie Garcia told KTRK that the family pet Chihuahua, named Guero, went along for a trip with her husband and a friend on July 13. The men were stopped by a Houston police officer for failing to use a turn signal, and a search of the vehicle turned up prescription medication, which Garcia said belonged to the passenger. 

The officer took both men into custody. And when the tow truck arrived, the dog was placed on the side of the road.

Garcia placed "lost" dog signs around the area where Guero was last seen but three days later, she was notified that the 14-year-old pet was lying dead on Eastex Freeway. 

The mayor of Houston has apologized to the family and Houston Police Department also expressed its condolences.
