If you thought someone was giving some substance to an elderly person, something beyond their prescribed meds, but couldn't prove it:
1. What would you do?
2. Would you hire an independent nurse to take a blood sample for testing, if you found the rights?
3. Do you think legal, or some other, representation would be in order?
4. Do you know of steps that would need to be taken, for instance, if a blood test proved foul play, could/would you have police agents go to the residence with you?
5. Anyone know what steps, if any, should be taken?

This probably sounds serious... IT IS!
If anyone can give me information, I sure would appreciate it.
I'd also appreciate you asking any and all people you know who might have ideas on how to approach this concern, both delicately and thoroughly....
Time is important!
