I can well understand that there are people who have not yet come forward, who may be able to contribute significantly to justice for Suzanne. I can think of a couple right off the top of my head, and a few more in Salida who may be very reluctant to tell what they know. I also think that some of these people could be issued a subpoena and testify at some point in future, but that LE would prefer them to volunteer what they know. I think many states have a type of subpoena, frequently used in domestic violence cases, where the respondent has to show up in closed court to testify initially in front of a judge. I know I've had students over the years subpoenaed (reluctantly) into criminal cases both inside and outside their families, including murder cases.
