Texas' debate over arson science is reignited

It wasn't too difficult to convince a jury that Garland Leon "Butch"
Martin of Midland was a wife abuser and a baby killer.
The day in 1998 that his common-law wife, Marcia Pool, threatened to
leave him because of abuse, their house went up in flames, killing Pool
and their 20-month-old daughter. Martin, who was not at home, was
convicted of arson and is serving three concurrent life sentences.
But now, modern science may impugn the jury's decision. Martin's
conviction is one that some believe was based at least in part on
"junk" science.
A number of forensic scientists and others are calling for additional
reviews of arson-murder cases like Martin's because evidence was
analyzed by methods now called into question or proved wrong. Members
of the Texas Forensic Science Commission say they don't have the
jurisdiction to investigate these cases, but they have told the Texas
Innocence Project to team up with the State Fire Marshal's Office to
determine whether the state has incarcerated people for arson-murders
based on outdated science.
"To the extent that this review goes on, it is because of the voluntary
participation of these agencies who think it's the right thing to do,"
commission attorney Lynn Robitaille said. The commission is expected to
discuss the issue in more detail at its meeting Friday.
At issue, however, is whether a comprehensive review of such cases can
or will be done. Skeptics say that the assessments would require a lot
of time and resources and that such extensive work may not be possible.
An estimated 700 to 900 people are in Texas prisons for arson-related
crimes, according to various sources. Of those, about 100 are from
Tarrant and Dallas counties, state inmate records show.
Furthermore, the marshal's office, which early on pledged to assist
such a review, is in transition. Any success in reviewing cases may
largely depend on whether the new state fire marshal makes such an
effort a priority, some say.
In a statement responding to questions from the Star-Telegram, the
marshal's office said that it is still evaluating the commission's
recommendations and hasn't adopted any new procedures but that the
office's commitment to improve the quality of fire investigations in
Texas is unchanged.
The commission has urged the marshal's office to review its standards
for arson investigations because of concerns about its work in the case
of Cameron Todd Willingham. The former Corsicana mechanic was executed
in 2004 for the arson that killed his three young daughters.
Commissioners have said that Willingham's conviction was based on
outdated arson science.
Another obstacle to such a comprehensive review is that criminal
defense attorneys don't have the time to review such cases, either. And
if they did, it would be very costly, they say.
Plus, for every case that comes under scrutiny, someone has to
acknowledge that mistakes have been made. That may not be popular.
"Everybody's got a dog in the hunt," said Gerald L. Hurst, a
Cambridge-educated chemist and arson expert in Austin who is examining
Martin's case.
Inmate questionnaires and
student reviews
It's also unclear how many arson convictions need new interpretation of
the evidence.
Maybe only a handful of cases can be pinpointed to junk science, said
Jeff Blackburn, founder and head of the Texas Innocence Project. Many
more cases may be flawed because of misleading testimony about the
science used to back arson findings, he said.
It's too early to know, he said. "But we are completely devoted to
doing this," he said.
The Innocence Project will use the same methodology as in past reviews
of wrongful convictions.
It has swamped state prisons with multiple-page questionnaires for
inmates to fill out. That can gauge the need for a potential review of
a case, Blackburn said.
Once an inmate responds, the information will likely be entered into a
massive database for review, Robitaille said.
"This is a time-consuming process," she said.
Law interns and students will likely review data and highlight cases.
The more promising ones will be reviewed by Blackburn and other
Innocence Project attorneys. Then, the State Fire Marshal's Office will
likely weigh in.
"There's nothing for them to do until they have a list of cases to look
at," Robitaille said.
To examine such cases at the local level, teams of law students could
be enlisted to read court testimony and cull transcripts, said former
Forensic Science Commissioner Lance Evans, a Fort Worth criminal
defense attorney. Pro bono committees of local attorneys could be
organized to work on individual cases. Those entities could prioritize
cases based on pleas.
Hurst, however, says some interpretations of fire evidence are so bad
that they can be eyeballed and spotted in two hours.
"It can be done," Hurst said. "This is not an impossible task. I know
because that is what I do."
Case is said to show the need
for review
The clincher for Martin's conviction was a pour pattern in the home's
master bedroom that indicated the presence of a flammable liquid:
Norpar in lamp oil.
Today's fire scientists note that Norpar is used in a wide range of
household products. That puts the arson finding in question, defense
experts said.
The case demonstrates why some felony arson convictions need reviewing,
Evans said.
"Our investigation with the Forensic Science Commission showed that a
significant portion of fire investigation 'science' was little more
than an oral history passed down from older arson investigator to newer
arson investigator -- almost like an apprenticeship program," Evans
said.
For example, more than a decade ago, certain pour patterns and heat
indicators prompted investigators to immediately conclude that
accelerants were present. With that, an arson finding was determined,
even without supporting lab results.
Today, fire scientists like John J. Lentini, who is based in Florida,
know that a number of cases have no such absolutes and that in some
cases, the cause of a fire may never be determined.
But, he said, arson often isn't subtle.
"It's usually pretty obvious when you walk in and you find gas cans or
it smells like gasoline or you find something that's obvious," Lentini
said.
Hurst calls the older methods "folklore" and he estimates that at least
100 of the 700-some arson felony cases were based on that. The science
in cases older than 15 years was almost always in question, he said.
But even "modern" cases need scrutiny, he said. "They still get it
wrong because they're still using those outdated methods," he said.
Take the 2004 case of Ron Winn of North Richland Hills. He was on his
way to prison until fire science exonerated him.
Winn was remodeling his house when it burned down. A police dog
identified accelerant after a few moments in the charred house.
Winn "was arrested initially," Fort Worth defense attorney Richard
Henderson said. "The arrest was videotaped. The police were all over
him."
Henderson then brought in Hurst, who conducted a forensic analysis.
It turned out that Winn's wife had brought home a jug of gasoline for
the lawn mower. She put the jug on the kitchen counter, where he was
working with equipment on an extension cord. As he was working, the
cord shifted, knocking down the gas jug and a lamp, breaking a light
bulb and setting the house on fire, Hurst said.
"People, use your head," Hurst said. "People don't get into heavy-duty
remodeling and actually putting in physical labor and then they just
decide to burn the place down while in the middle of a project.
"Give me a better motive."
Prosecutors eventually dismissed the case, Henderson said.
"They did the right thing," he said.
