(a) A lawyer shall not make an extrajudicial statement that a reasonable person would expect to be disseminated by means of public communication if the lawyer knows or reasonably should know that it will have a substantial likelihood of materially prejudicing an adjudicative proceeding.
(b) A statement referred to in paragraph (a) ordinarily is likely to have such an effect when it refers to a civil matter triable to a jury, a criminal matter, or any other proceeding that could result in incarceration, and the statement relates to:
(1) the character, credibility, reputation or criminal record of a party, suspect in a criminal investigation or witness, or the identity of a witness, or the expected testimony of a party or witness;
(2) in a criminal case or proceeding that could result in incarceration, the possibility of a plea of guilty to the offense or the existence or contents of any confession, admission, or statement given by a defendant or suspect or that person's refusal or failure to make a statement;
(3) the performance or results of any examination or test or the refusal or failure of a person to submit to an examination or test, or the identity or nature of physical evidence expected to be presented;
(4) any opinion as to the guilt or innocence of a defendant or suspect in a criminal case or proceeding that could result in incarceration;
(5) information the lawyer knows or reasonably should know is likely to be inadmissible as evidence in a trial and would if disclosed create a substantial risk of prejudicing an impartial trial; or
(6) the fact that a defendant has been charged with a crime, unless there is included therein a statement explaining that the charge is merely an accusation and that the defendant is presumed innocent until and unless proven guilty.
(c) Notwithstanding paragraph (a) and (b)(1)-(5), a lawyer involved in the investigation or litigation of a matter may state without elaboration:
(1) the general nature of the claim or defense;
(2) the information contained in a public record;
(3) that an investigation of the matter is in progress, including the general scope of the investigation, the offense or claim or defense involved and, except when prohibited by law, the identity of the persons involved;
(4) the scheduling or result of any step in litigation;
(5) a request for assistance in obtaining evidence and information necessary thereto;
(6) a warning of danger concerning the behavior of a person involved, when there is reason to believe that there exists the likelihood of substantial harm to an individual or to the public interest; and
(7) in a criminal case:
(i) the identity, residence, occupation and family status of the accused;
(ii) if the accused has not been apprehended, information necessary to aid in apprehension of that person;
(iii) the fact, time and place of arrest; and
(iv) the identity of investigating and arresting officers or agencies and the length of the investigation.
