Sections 610.100.3 and 610.100.4, RSMo, state that the agency has the authority to withhold the disclosure of records that may otherwise be subject to disclosure under two circumstances. First, if the agency has an articulable concern over the safety of a victim, witness, or other person if the record is revealed. Second, disclosure is not necessary if the criminal investigation is likely to be jeopardized. 

Attorney General Opinion No. 200-94 states that if criminal charges are filed, disclosures of police reports should occur under the applicable Rules of Criminal Procedure promulgated by the Missouri Supreme Court. As a result, the defendant is generally required to seek his disclosures from the prosecuting attorney and not the law enforcement agencies directly.

The information that is generally available or open regarding a 911 call is the "incident information" - the date, time, specific location, and immediate facts and circumstances of the call. The recording is inaccessible to the public. Section 610.150, RSMo.
