anon- “He” is just a term for an anonymous person. I wasn’t being sexist.
I checked Snopes and they said that some of the deaths are still being investigated, after 10-20 years. “The FBI is still investigating the deaths…suspicious”.
This means its a) a cold-case and they have no leads
b) they cannot release the truth…. or wont. so they say its #a.
Also, some of the deaths were ruled accident, like the two boys on the train tracks. But the medical examiner made many mistakes in his past, and he said they overdosed and fell asleep. So his testimony cant be trusted.
