(plaintiff sought determination that they need not defend nor indemnify defendant (insured) in negligence action brought against defendants (teenage boys) for damages sustained by prank pulled by defendants; defendants placed Styrofoam deer on road at night; driver came over hill, spotted what appeared to be a live deer and veered to miss it, but lost control of the vehicle and overturned; court determined that, as a matter of law, placement of deer on road did not cause resulting harm because evidence showed that other cars had avoided the deer - defendants' conduct and resulting harm not intrinsically tied together; thus summary judgment for plaintiff not proper - jury must weigh facts to determine whether defendants intended or expected resulting harm and, if so, whether plaintiff's policies provided coverage; as for one policy in issue, exclusionary language was different and insurer under no duty to defend or indemnify insureds).
