An indictment for murder may be found at any time after the death of the person alleged to have been murdered.

Such independent evidence shall be admissible during trial and shall not consist exclusively of the opinions of mental health professionals. An indictment for an offense set forth in sections 17, 18, 19 and 21 of said chapter 265 or section 17 of chapter 272, for conspiracy to commit any such crime, as an accessory thereto, or any 1 or more of them may be found and filed within 10 years after the date of commission of such offense. An indictment for any other crime shall be found and filed within 6 years after such crime has been committed. Any period during which the defendant is not usually and publicly a resident within the commonwealth shall be excluded in determining the time limited.
