I agree with the idea of surveillance. Some camcorders have a mode that will work like that, or there are some inexpensive cameras that can be purchased. You know who you suspect, what you need is to veryify that it is or is not happening.
Lock away real valuables or heirlooms that you absolutely do not want taken, then set the change jar or cigarette stash for surveillence.
You do need to talk with DH, not exactly in an accusatory way, but in a "we have a problem" manner where you focus on solutions, not blame. If you are blaming DSD, regardless of how accurate, you are pitting your husband between the two of you. If you are focusing on helping her, you are working as a team to give her a better chance at life.
