It’s now been three days since the grisly discovery of four bodies in an apartment in Chester.

And what we don’t know still outweighs what we do.

We now know the names of the four victims, two women in their early 20s, a 3 year-old child, and a 28-year-old man.

But we still have no inkling of what happened in the tidy apartment on Keystone Road. We don’t know how those four people died, or why.

We don’t know who or what circumstances led to the death of Lindsay Cassidy, 23, and her 3-year-old son Kolby O’Brien, along with Cassidy’s friend Michelle Fynes, 22, and Fynes’ boyfriend, John Michael Bryant, 28.

Autopsies on the bodies were performed by the Delaware County Medical Examiner’s office. But M.E. Dr. Fredric Hellman has indicated the manner and cause of death remains pending. He says he wants to do more testing, including awaiting the findings of outside lab work. That would include toxicology tests, which often can take weeks to come back.

This is not unusual, especially when it comes to Hellman. His reputation is someone who is thorough, meticulous, but not necessarily speedy.

We’ve been accustomed to reporting manner and cause of death as “pending” as Hellman goes about his work.

The one thing family members likely do not want to hear is that the investigation has not yet reached a conclusion in terms of how their loved ones died.

Likewise investigators now must await a ruling from Hellman as they go about trying to decipher the mystery of what happened inside that apartment.

But that’s the way it is. Four people are dead. Hellman will meticulously go about putting together his findings.

The only thing everyone else can do at this point is wait on his findings.
