A teenager was shot and killed at a gas station in southeast Houston on Saturday evening and two others were wounded, according to police. 

The two wounded teens, described as "juveniles" by Houston Police Assistant Chief Patricia Cantu, were taken to a hospital down the street by a bystander who witnessed the shooting.
