I'm not sure who you spoke with, but none of the staff are males. I've spoken with the staff. Outside Brazos County won't be happening with the staffing level they have right now. Maybe once procedures are down pat it could be easier to conceive, but the simple fact of needing someone available 24/7 just to let another county bring a body (via funeral home since Brazos ME won't be responding out of county to pick up/investigate at the scene) is a burden not many employees will just keep doing in perpetuity with such small numbers of staff.
Currently, the plan seems to be that all staff will be rotating on-call duties, not just the investigators. That's 6 to rotate right now, if the manager, doctor, admin assistant, and tech jump in to help the two field investigators. What happens when there's more than one death at a time (which isn't uncommon). What happens when someone gets sick? Needs to go on vacation? Is an admin assistant and tech going to even have the same training as the field investigators? Is it fair to ask two investigators to literally live their whole life on call? Those are hard questions to just cover Brazos, much less the surrounding area.
