You are serving a on a jury for a murder trial

You are serving a on a jury for a murder trial. The evidence presented trial was largely circumstantial and, in your mind equivocal. Durin closing the prosecutor argued that you must find the defendant guilty because he confessed to the crime. The defense attorney immediately objected and the judge sternly instructed you to disregard the prosecutor's statement. While you do not know exactly what happened, you suspect that he confession was excluded because of some procedural error. Would you be able to ignore the prosecutors statement in your deliberations? Should you ? Would you tell the judge if the jury members discussed the statement and appeared to influence by it ?
