HOUSTON -- For years the number of victims in Houston's most notorious serial killings has been 28, but a Houston writer says she s found that there could be one more victim.

From 1971 to 1973 young men were the targets of Dean Corril and his teenage accomplices David Owen Brooks and Elmer Wayne Henley Jr. The victims were abducted, raped, tortured and murdered.

Twenty-eight bodies were found, two of those victims are still unidentified.

Barbara Gibson is writing a book on the Houston Mass Murders and played a key role in last month's discovery that the body of Michael Baulch had been misidentified.

Earlier this month Gibson visited Henley in prison and said she was in for a shock. She said she was quizzing him about the 17 bodies found buried in a southwest Houston boat house in 1973 and when it came to the case of Mark Scott she said Henley didn t think the victim was buried there.

At the time the bodies were found Scott's family did not think that the body identified as their son was correct. Neither does Henley.

I argued that and argued that and argued that, Henley said in an audio recording of the author s interview with him.

In 1994, more than 20 years after the crimes, DNA tests led Harris County Medical Examiner Joseph Jahemczyk to issue a final ruling and death certificate for Mark Scott.

But there was a problem.

Jahemczyk wanted me to do and say things that I wasn't willing to do and say, Henley said.

For example, a statement in the autopsy of the body identified as Mark Scott, which suggests that Henley told investigators Scott was buried in the boat shed where the body was found.

But Henley said he's never said that because he knows where Scott was buried.

It was High Island. In the Sand. Fetal Position. Head up, Henley said in the recording.

Another half-dozen victims were found buried on High Island.

Now the Harris County Medical Examiner s office is re-testing using current technology DNA of the Scott family.

If that finds no match, Gibson said it is possible that there is another victim in the string of cases that hasn t been identified.

The 1994 DNA testing showed that 1.5 percent of all white persons would match, a small margin, but 10 out of a thousand would also match in that case.

Current testing is much more accurate.

Henley killed Corril in 1973. The search for victims ended abruptly in August of that year, even though a leg bone and pelvis were found suggesting at least one more victim.

Forty-two young men were listed as missing in Houston during the timeframe of the murders.

Results of new DNA testing in the Scott case are expected in January.
