HOUSTON – A construction supervisor was shot and killed -- and possibly robbed at a home construction site in northeast Houston, Harris County deputies said.

Deputies said the construction supervisor was approached by two males may have been targeted, as there have been other reports of construction workers in the area being robbed.

The shooting was reported around noon on Pueblito Verde Way, near Channelview Independent School District's two campuses, Alice Johnson Jr. High and McMullan Elementary.
