The fingerprint on a door, the eyeglasses left behind, and the witness who tied Manson to the murders

The word was on the front door, written in blood.

PIG.

Five people were dead inside the house at 10050 Cielo Drive in Benedict Canyon, Los Angeles, on the night of August 9, 1969.

The crime looked random.

The killers left no obvious motive, no clear connection to the victims.

Then investigators found a fingerprint on a door at the Tate residence.

It was later matched to Patricia Krenwinkel.

And there was a pair of eyeglasses, found at the scene.

The glasses were traced to a man who identified Charles Manson.

Two small objects.

A print on a door, a pair of lenses on the ground.

That is all it took to begin unraveling a seemingly random crime.

The exact location of the fingerprint on the door is not specified in the source.

The record does not establish where, precisely, the print was found.

Only that it was there, and that it matched.

Not because the print was dramatic.

But because it was physical, it was silent, and it stayed.

A fingerprint does not confess.

It does not explain itself.

It simply remains, pressed into the surface, waiting to be compared.

The eyeglasses were the same.

They did not name their owner.

They were traced, step by step, to a man who then identified Charles Manson.

What did the man say?

The source does not record his words.

What the source records is the chain: the glasses, the man, the name.

These two pieces of physical evidence would become central to the case.

They were the start of the forensic discovery.

The door held a word.

The door also held a print.

Both were left behind on a night when five people were murdered.

TWO NIGHTS

Five people died at 10050 Cielo Drive on the night of August 9, 1969.

Sharon Tate was eight and a half months pregnant.

Also killed were Abigail Folger, her boyfriend, Jay Sebring, and two others.

The killers wrote “PIG” in blood on the front door.

The following night, August 10, 1969, Leno and Rosemary LaBianca were murdered in their Los Feliz home.

At the LaBianca scene, “Death to Pigs” and “Helter Skelter” were scrawled in blood.

Two nights. Two houses. Two sets of dead.

The crimes were discovered the following mornings by the victims’ associates and family.

The exact time of the murders is not in the record.

The initial investigation was hampered by a lack of suspects.

It was hampered by the randomness of the killings.

Why these people?

Why these houses?

Why these nights?

That would require evidence.
