New Records Raise Questions About Unidentified Remains in Rhonda Johnson and Sharon Shaw Investigation

By Investigative Reporter Tammy Rose

More than five decades after the murders of Rhonda Johnson and Sharon Shaw, newly reviewed records are raising questions about additional human remains found in the area. The records also raise the possibility that investigators once considered whether another person played a role in the case.

Rhonda Johnson, 14, and Sharon Shaw, 13, disappeared from Galveston County in August 1971. Authorities later recovered their skeletal remains in and around Clear Lake along Galveston Bay.

The investigation continued for decades as detectives worked to identify remains, examine evidence and determine whether the discoveries connected to the two girls.

The records do not prove that another victim or another killer was connected to the murders. However, they show how much uncertainty investigators faced during the early stages of the case.

Remains of Sharon Shaw and Rhonda Johnson Identified

On January 3, 1972, two boys fishing in Clear Lake discovered a human skull floating in the water.

Authorities later identified the skull through dental records as belonging to Sharon Shaw. Investigators also reportedly found a crucifix around the jawbone that Sharon’s mother identified as her daughter’s.

About six weeks later, searchers recovered additional skeletal remains in a marsh near Clear Lake. Authorities identified one set of those remains as belonging to Rhonda Johnson.

The discoveries confirmed that both girls had died, but investigators could not determine their exact causes of death from the remains.

The identification resolved the girls’ missing-person cases, but other remains recovered during that period created additional questions.

Michael Lloyd Self Was Convicted

Investigators eventually focused on Michael Lloyd Self, who worked as a gas station attendant in the Webster/Clear Lake area. Authorities charged Self in connection with the murders of Rhonda Johnson and Sharon Shaw

A jury convicted Self of murdering Sharon Shaw and sentenced him to life in prison. The court record confirms that his conviction involved Sharon’s murder; he was not convicted of Rhonda Johnson’s murder. 

Self later said police had threatened and physically abused him until he confessed. Questions about whether investigators obtained a false or coerced confession followed the case for decades. A federal judge once recommended relief based on the confession issue, although a later appeals court decision allowed the conviction to stand. 

Edward Harold Bell Became an Alternate Suspect

In 1998, convicted killer Edward Harold Bell claimed responsibility for the murders of several young women and girls in the Galveston-area region. His statements included two girls from Webster who disappeared in August 1971, which investigators associated with Rhonda Johnson and Sharon Shaw.

Bell became an alternate suspect in their murders, but authorities never charged him in the case. Investigators reportedly lacked physical or biological evidence that conclusively connected Bell to the girls’ deaths. 

Bell’s claims increased doubts about Self’s conviction, but they did not officially resolve who killed Rhonda and Sharon.

Questions Surrounding Other Remains

Records reviewed by Investigative Reporter Tammy Rose indicate authorities recovered an unidentified torso in September 1971.

Investigators reportedly found clothing or personal items with or near the remains that they believed belonged to Phillip Manning. Those items initially led authorities to consider whether the torso might be Manning’s.

Authorities later located Manning alive in Louisiana. That confirmed the torso was not his.

The discovery still raised questions about the unidentified victim’s identity and whether another victim—or possibly another killer—may have been connected to the investigation. However, the records reviewed so far do not establish that the torso was connected to the murders of Rhonda Johnson or Sharon Shaw.

Records Detail Manning’s Background

The records also include criminal-history and case information connected to Phillip Manning. That material may help explain why investigators examined his possible connection to the case.

However, the records do not establish that Manning killed Rhonda Johnson, Sharon Shaw or anyone else. The information surrounding him remained circumstantial, and the records reviewed so far do not show that authorities filed a case against him in connection with the girls’ murders.

Investigators Faced Difficult Conditions

The discoveries occurred during a period when severe weather affected portions of the Texas Gulf Coast.

Tropical storms Edith and Fern moved through the region in September 1971, potentially complicating searches, recovery efforts and investigators’ ability to determine where remains had originally entered the water.

Water movement, weather conditions and the passage of time may have made it more difficult to connect separate remains to specific locations or victims.

Investigators in 1971 also did not have access to the DNA testing and modern forensic databases available today.

Identifications often depended heavily on dental comparisons, physical characteristics and other available medical evidence.

Was Another Killer Suspected?

The records raise an important question: Did investigators believe the additional remains pointed to another victim—or possibly another offender operating in the area?

The documents reviewed so far do not provide a definitive answer.

They instead show that authorities were dealing with several discoveries, uncertain identifications and incomplete information during the earliest stages of the investigation.

Any suggestion that another killer was involved should be treated as a theory unless additional police reports, forensic findings or official statements support it.

Questions That Still Need Answers

Several important questions remain:

Who exactly was Phillip Manning?

Why did investigators connect his name to the torso?

Was the torso ever conclusively identified?

Did Manning have any documented connection to Rhonda Johnson or Sharon Shaw?

What did investigators believe before the girls’ remains were fully identified?

Are additional reports or forensic records still available?

Those questions may be important in understanding not only what investigators knew, but also how the case evolved during its earliest months.

Investigation Continues to Draw Interest

The murders of Rhonda Johnson and Sharon Shaw remain among the most discussed cases connected to the Texas Gulf Coast.

Decades later, old reports, forensic findings and previously overlooked names continue to generate new questions.

The records do not yet prove that another killer was involved. But they show that the investigation may have been more complex than the public understood—and that parts of the story may still be missing.

Investigative Reporter Tammy Rose will continue reviewing available records and seeking documentation that could clarify the identity of the additional remains and Phillip Manning’s possible connection to the investigation.
