“[J]uror's affidavit demonstrating the injection into the
deliberative process of extraneous prejudicial information was admissible under
the "extraneous prejudicial information" exception to 12 O.S. 2011
§2606(B). Furthermore, counsel were entitled to rely on the foreperson's
guarantee to the trial court that she would not allow her professional
expertise to override the testimony presented. Because there is evidence to the
contrary, we hold that there was no abuse of discretion in ordering a new trial
for juror misconduct during deliberations.” http://www.oscn.net/applications/oscn/DeliverDocument.asp?CiteID=465459
