Within seven days after receipt of the names of defendant’s proposed alibi witnesses, or within such other time as is ordered by the court, the prosecuting attorney shall file and serve upon the defendant or his counsel the names of the witnesses known to the prosecuting attorney which the state proposes to offer in rebuttal to discredit the defendant’s alibi at the trial of the case. Both the defendant and the prosecuting attorney shall be under a continuing duty to disclose promptly the names of additional witnesses which come to the attention of either party subsequent to filing their respective witness lists as provided by this section so that reciprocal discovery rights are afforded both parties.
