Did Genene Jones Kill As Many As 60 Children As A Pediatric Nurse?
Quotes: "The strange deaths raised enough suspicion among ICU doctors that Genene Jones was somehow involved, forcing the hospital to remove her.However, desperate to prevent bad press, hospital administrators refused to fire Jones or call the police." (Red Text added.)
"In fact, she gained something out of it, being let go with stellar recommendation letters and her professional reputation still intact. Jones chose to leave the hospital, and the deaths mysteriously stopped."
"The only case that prosecutors could decisively link to Jones involved Chelsea McClennan, a 15-month-old baby who arrived at the clinic forroutine immunization shots." (Red text added. Story said she administered succinylcholine instead.)
