Some possible reasons the focus distance in the image was closer to the camera than where the autofocus point used was superimposed on the scene at the time the image was taken:

• You locked focus and then recomposed. If you are using AF-S focus mode once focus is confirmed the camera will hold the focus at that distance as long as the shutter button is half pressed (or any AF back button is pressed).
• You zoomed in or out after locking focus. Most lenses do not hold focus when the focal length is changed. Those that do are called parfocal lenses and true parfocal lenses are very expensive, usually in the five figure (USD) range. They're mostly used by cinematographers. Some cheaper zoom lenses with fairly narrow maximum apertures can appear to be effectively parfocal because the extended depth of field due to the smaller aperture masks the change in focus distance as the lens is zoomed from longer focal lengths to shorter focal lengths (but doesn't work as well if the lens is zoomed from shorter to longer focal lengths).
• The area of sensitivity for each AF "point" is usually much larger than the square you see in the viewfinder. The camera will AF on whatever it detects with the greatest contrast anywhere within the active AF area.

If those don't solve your issue, please see the more general question How do I diagnose the source of focus problem in a camera?

This answer to the above linked questions covers a wide variety of possible causes of focusing issues and provides a plethora of links to other, more specific questions here at Photography SE about each possible cause.
