Zend join left with multiple result from left table

Question

I am trying to select one item form the items table and join the second table (images). The table images will have multiple results for each item. The problem is that the result join is bringing just one result instead of an array with all images data.

The code

    $select = $this->select();
    $select->setIntegrityCheck(false);
    $select->from($this)
           ->joinLeft('items_images', 'items.item_id = image_item_id')
           ->where($where);
    $result =  $this->fetchRoll($select);

What I am missing?

Thanks
