A man was killed Wednesday at a Valero gas station, less than a mile from the scene of a shooting death reported earlier in the afternoon, police said.

Houston police said the man died at the gas station in the 6200 block of West Airport Boulevard. Homicide investigators were on the scene.

A few minutes before announcing the man’s death, Houston police reported a shooting death about half a mile west of the location at 6725 West Airport Boulevard.

It’s unclear whether the two deaths are related.
