Why is the marker shadow not showing on the google map?

Question

Google

It seems I'm doing everything right, but the marker is displayed and the shadow is not.
Here is the code:

function setMarkers(map, locations) {

        var image = new google.maps.MarkerImage('media/images/layout/other_bg/map_marker.png',

            new google.maps.Size(55,68),
            new google.maps.Point(0,0),
            new google.maps.Point(27.5,68)

        );

        var shadow = new google.maps.MarkerImage('media/images/layout/other_bg/map_marker_shadow.png',

            new google.maps.Size(60,63),
            new google.maps.Point(0,0),
            new google.maps.Point(30,68)

        );

       for (var i = 0; i < locations.length; i++) {
               var beach = locations[i];
               var myLatLng = new google.maps.LatLng(beach[1], beach[2]);
               var marker = new google.maps.Marker({
                       position: myLatLng,
                       map: map,
                       shadow: shadow,
                       icon: image
               });
       }
}

The paths are correct.

Note: Marker shadows were removed in version 3.14 of the Google Maps JavaScript API. Any shadows specified programmatically will be ignored.
Shadows have been removed from version 3.14
