Overview


On May 25, 2000, Baker was last seen at a Sheetz convenience store along Route 18 in Pymatuning Township, Pennsylvania. According to her fiancé, she left the store alone in her car—a dark blue 1988 Honda Accord.

Later that day, she made a chilling phone call to Crea. She reportedly told him she was “in danger” and could not return home, promising to call again in a few days. She never did.

A witness later saw her driving toward Sharon, Pennsylvania, but that would be the last confirmed sighting.


The Disappearance of Sandra Kay Baker: A Cold Case That Still Haunts Pennsylvania

The disappearance of Sandra Kay Baker—often called “Sandy”—remains one of Pennsylvania’s most perplexing unsolved cases. More than two decades after she vanished in 2000, investigators continue to believe she was the victim of foul play, yet no one has ever been charged.

Who Was Sandra Kay Baker?

Sandra Kay Baker was a 46-year-old woman living in Delaware Township, Mercer County, Pennsylvania. She was engaged to William “Billy” Crea Jr., and the couple was planning to marry later that year. Friends and family described her as someone who maintained regular contact with loved ones—making her sudden disappearance all the more alarming.

On May 25, 2000, Baker was last seen at a Sheetz convenience store along Route 18 in Pymatuning Township, Pennsylvania. According to her fiancé, she left the store alone in her car—a dark blue 1988 Honda Accord.

Later that day, she made a chilling phone call to Crea. She reportedly told him she was “in danger” and could not return home, promising to call again in a few days. She never did.

A witness later saw her driving toward Sharon, Pennsylvania, but that would be the last confirmed sighting.

The Missing Car and Lost Evidence

The day after her disappearance, Baker’s car was found abandoned at the Shenango Valley Mall. However, a critical investigative mistake occurred:

The vehicle was repossessed by a finance company
It was later sold at auction
Police did not locate it until years later, when any potential evidence had been destroyed

This misstep is widely considered one of the most damaging setbacks in the case.

A Prime Suspect Emerges

By 2005, investigators publicly identified William Crea Jr., Baker’s fiancé, as a suspect.

The case took a dramatic turn when a private investigator, Clifford Stephen Aley Jr., claimed that Crea had confessed to murdering Baker during an argument, allegedly strangling her and hiding her body.

However, the credibility of this claim quickly unraveled:

Aley failed a polygraph test
He later admitted to lying to police
He was convicted of hindering the investigation and served prison time

With no physical evidence and no body recovered, prosecutors could not move forward with charges.

Official Status of the Case

Authorities have consistently stated they believe Baker was murdered. Yet, the case lacks the evidence needed for prosecution:

No confirmed location of her remains
No forensic evidence tying a suspect to a crime
Conflicting and unreliable witness statements

Sandra Kay Baker was declared legally dead in 2008, but her case remains officially unsolved.

Latest Investigation Developments

While there have been no recent arrests, the case is still considered open by the Pennsylvania State Police. Key points regarding its current status include:

Investigators continue to classify it as a suspected homicide

– The primary suspect, William Crea Jr., was never charged
– Leads tied to the alleged confession were discredited
– The loss of the vehicle evidence remains a major obstacle

Despite the passage of time, cold case advancements—such as DNA technology and renewed public interest—leave open the possibility of future breakthroughs.

Why the Case Still Matters

Sandra Kay Baker’s disappearance highlights how critical early investigative decisions—and lost evidence—can shape the outcome of a case. It also underscores a painful reality: even when authorities strongly suspect foul play, justice can remain out of reach without physical proof.

Anyone with information is still encouraged to contact the Pennsylvania State Police.
