I totally have NO problems with her prescription drug list. Nothing on there should have been a problem or caused her death.
The heavy metal I zero in on because of its rarity is Platinum. I have seen most, but not all, of the others in tox. screens before. ( Not post- mortem though).
The extremely cell- toxic drug Cisplatin, is given as a chemotherapy drug for cancer. It would probably show up as Platinum in the hair sample.
IF someone was dosing her and her husband with heavy metals, not only were they criminal, they were stupid. She wasn't cremated, thus the substances show up in hair and other tissues.
Also, Cisplatin is only given via IV administration. Here's the wiki on the only platinum containing substance I know of:
Cisplatin - Wikipedia, the free encyclopedia
Agree that her husband's body should be tested, and the lady in the house, if she is still alive, is probably also very ill.
Because all 3 had the same symptoms, I believe there is a 4th person involved.
Financial gain would seem the most likely motive for Brittany's death, and perhaps that of her husband who was probably her beneficiary.
Just how sick IS the woman upstairs?
One last thing: I haven't checked today's news, but the NE is the only source reporting this. I have seen the copies of the reports and believe them to be valid, but why hasn't another source reported on this?
Is someone trying to suppress the results? Maybe LE has asked her father to not publicize the reports pending a criminal investigation?
The key to solving this, IMO, will be the source of the platinum.
