Jim Fowler has been struck twice by light­ning. A retired house painter in Oklahoma City, Okla., Fowler lived through his 19-year-old son Mark’s arrest in 1985 for mur­der­ing three peo­ple in a gro­cery-store holdup. Mark was sen­tenced to death. A year lat­er Fowler’s moth­er Anne Laura was raped and mur­dered, and a man named Robert Lee Miller Jr. was sen­tenced to die for the crime. The same Oklahoma City police depart­ment foren­sic sci­en­tist, Joyce Gilchrist, tes­ti­fied at both tri­als. But DNA evi­dence lat­er proved she was wrong about Miller. He was released after 10 years on death row, and a man pre­vi­ous­ly cleared by Gilchrist was charged with the crime. Fowler can’t help won­der­ing if Gilchrist’s tes­ti­mo­ny was equal­ly inept at the tri­al of his son Mark, who was exe­cut­ed in January.

Last week gave Fowler even more rea­son to won­der. A state judge ordered a man named Jeffrey Pierce released after serv­ing 15 years of a 65-year sen­tence for rape. Gilchrist placed him at the scene of the crime, but DNA evi­dence proved he was not the rapist. In response, Oklahoma Governor Frank Keating launched a review of every one of the thou­sands of cas­es Gilchrist touched between 1980 and 1993, start­ing with 12 in which death sen­tences were hand­ed down. But in anoth­er 11 of her cas­es, the defen­dants have already been put to death. The state is giv­ing the Oklahoma Indigent Defense System $725,000 to hire two attor­neys and con­duct DNA test­ing of any evi­dence ana­lyzed by Gilchrist that led to a con­vic­tion. A pre­lim­i­nary FBI study of eight cas­es found that in at least five, she had made out­right errors or over­stepped the accept­able lim­its of foren­sic sci­ence.” Gilchrist got con­vic­tions by match­ing hair sam­ples with a cer­tain­ty oth­er foren­sic sci­en­tists found impos­si­ble to achieve. She also appears to have with­held evi­dence from the defense and failed to per­form tests that could have cleared defendants.

It’s a bit­ter con­vo­lu­tion of fate that Gilchrist should be based in Oklahoma City, the last place one would expect to find com­pelling argu­ments against the death penal­ty. Her sto­ry can’t help but give Oklahomans pause about the qual­i­ty of jus­tice met­ed out by their courts. Says Gilchrist’s lawyer, Melvin Hall: The crit­i­cism of her around here is sec­ond only to that of Timothy McVeigh.” But the alle­ga­tions also under­score a nation­al prob­lem: the some­times dan­ger­ous­ly per­sua­sive pow­er of court­room sci­ence. Juries tend to regard foren­sic evi­dence more high­ly than they regard wit­ness­es because it is pur­port­ed­ly more objec­tive. But foren­sic sci­en­tists work so close­ly with the police and dis­trict attor­neys that their objec­tiv­i­ty can­not be tak­en for granted.

Gilchrist told TIME in an inter­view last week that she’s bewil­dered by her predica­ment. I’m just one enti­ty with­in a num­ber of peo­ple who tes­ti­fy,” she says. They’re key­ing on the neg­a­tive and not look­ing at the good work I did.” In her 21-year career with the Oklahoma City police, she had an unbro­ken string of pos­i­tive job eval­u­a­tions and was Civilian Police Employee of the Year in 1985. Her abil­i­ty to sway juries and win con­vic­tions earned her the nick­name Black Magic.” In 1994 she was pro­mot­ed from foren­sic chemist to super­vi­sor. Until recent­ly, Hall says, she did not have a bad piece of paper in her file.” Now Gilchrist is on paid leave; in June she will face a two-day hear­ing to decide whether the police depart­ment should fire her. Meanwhile, her rep­u­ta­tion has been shattered.

The ham­mer blow came when Pierce, a land­scap­er who was con­vict­ed of rape in 1986, was released last week after DNA test­ing exon­er­at­ed him. He had been found guilty despite a clean record and plau­si­ble ali­bi large­ly because of Gilchrist’s analy­sis of hair at the crime scene. I’m just the one who opened the door,” said Pierce. There will be a lot more com­ing out behind me.”

Pierce lost 15 years, his mar­riage and the chance to see his twin boys grow up. But some fear there were oth­ers who paid even more dear­ly: the 11 exe­cut­ed defen­dants. The Oklahoma attor­ney gen­er­al has tem­porar­i­ly shut the gate on exe­cu­tion of the 12 still on death row in whose tri­als Gilchrist was involved. While the D.A.‘s office believes that the con­vic­tions will stand, these cas­es will be the first to be recon­sid­ered. Defense lawyers fear that the inno­cent who took plea bar­gains in the face of her exper­tise will nev­er come to light.

Gilchrist told TIME, There may be a few dif­fer­ences because of DNA analy­sis,” but she is con­fi­dent most of her find­ings will be con­firmed. I worked hard, long and con­sis­tent­ly on every case,” she says. I always based my opin­ion on sci­en­tif­ic find­ings.” She insists she did­n’t over­state those find­ings to please the D.A.‘s office or secure con­vic­tions. I feel com­fort­able with the con­clu­sions I drew.”

But defense lawyers say the Gilchrist inves­ti­ga­tion is long over­due. Her work has been mak­ing col­leagues queasy for years. In January 1987, John Wilson, a foren­sic sci­en­tist with the Kansas City police crime lab, filed a com­plaint about her with the Southwestern Association of Forensic Scientists. (The asso­ci­a­tion declined to take action.) Jack Dempsey Pointer, pres­i­dent of the Oklahoma Criminal Defense Lawyers Association, says his group has been fight­ing for an inves­ti­ga­tion almost since the time she went to work” at the lab. We have been scream­ing in the wind, and nobody has been listening.”

Police Chief M.T. Berry says it was­n’t until 1999 that the depart­ment had any rea­son to be sus­pi­cious about her work. That’s when fed­er­al Judge Ralph Thompson lit into her for untrue” tes­ti­mo­ny and the bla­tant with­hold­ing of unques­tion­ably excul­pa­to­ry evi­dence” in the rape and mur­der tri­al of Alfred Brian Mitchell. (Thompson over­turned the rape con­vic­tion but let the mur­der stand.) In March 2000 Gilchrist was put out to pas­ture at a police equine lab, where she says she had to do demean­ing tasks” like count test tubes.

Then this January, a dev­as­tat­ing memo from Byron Boshell, cap­tain of the police depart­men­t’s lab­o­ra­to­ry-ser­vices divi­sion, thud­ded onto Berry’s desk. It filled four three-ring binders and not­ed rever­sals and rep­ri­mands the courts had hand­ed Gilchrist, as well as the issues the pro­fes­sion­al jour­nals had tak­en with her work. Under her super­vi­sion, it said, evi­dence was miss­ing in cas­es in which new tri­als had been grant­ed or were under review; and rape evi­dence had been destroyed after two years, long before the statute of lim­i­ta­tions had expired. Gilchrist explained last week that she always fol­lowed estab­lished pro­ce­dures with evi­dence and that the memo was sim­ply the depart­men­t’s way of get­ting rid of her after she report­ed the sex­u­al harass­ment of a col­league. There is no doubt this [memo] is retal­i­a­tion,” says Gilchrist.

How did her career last this long? She could­n’t have got away with this if she weren’t sup­port­ed by pros­e­cu­tors, ignored by judges and police who did noth­ing,” says Wilson, who filed the orig­i­nal com­plaint against her 14 years ago. The police depart­ment was asleep at the switch.” The D.A.‘s office sim­ply says Gilchrist should not be tried in the media. But one pros­e­cu­tor, who declined to be named, lays blame on the aggres­sive tac­tics of D.A. Bob Macy, who’s proud to have sent more peo­ple to death row than any oth­er active D.A. in the country.

Which rais­es a more trou­bling ques­tion. How many oth­er Gilchrists are there? In Oklahoma City, Chief Berry has ordered a whole­sale review of the serology/​DNA lab. And while Governor Keating insists that no one has been exe­cut­ed who should­n’t have been, Pointer and the local defense-lawyers asso­ci­a­tion plan to re-exam­ine the cas­es of the 11 exe­cut­ed inmates. Nobody cares about the dead,” he says. The state is not going to spend mon­ey to find out that they exe­cut­ed some­one who might have been innocent.”
