I am new to posting, but have followed on Websleuths the Dr. Teresa Sievers case.
Just a couple of thoughts for what it is worth: Look at the custody situation with Dr. Teresa Sievers. Her mother went through so much and was ultimately able to relocate the children out of state. There was a paternal grandmother who also tried at the beginning to get custody. There were phone calls between the Sievers children and the father (in prison) that were required to take place. Also, Dr. Sievers husband plotted with out of state help to have his wife murdered per prosecutors and LE. Next, regarding nurses and PF, would PF not have access to medications that are lethal? PF works with animals. What does he have on hand? Regarding nurses in general, they have access to medication routinely. Just a few thoughts.
