The Ann Arbor Hospital Murders
 

 

 

 

 

 

31 year old Leonora Perez and 30 year old Filipina Narciso were suspected in numerous deaths at the Ann Arbor Hospital in 1975.

Pavulon and Curare were linked to the death of patients.  All charges ended up being dismissed due to lack of evidence.
Psychological tests proved their behavior patterns were "normal."   Eight men were confirmed dead of unnatural causes.
