JOHN GERDES: DNA specialist; testified he's being paid $100 an hour by defense; said Los Angeles police crime lab was ``by far'' the worst he'd seen and it should be shut down because of it's contamination levels; said he would have no scientific confidence in tests done on blood taken from Simpson Bronco because of poor evidence handling and lax security; said blood samples from glove at Simpson's estate, from sock and from crime scene gate had enough DNA that cross-contamination hadn't occurred; conceded that police technician didn't extract DNA from some blood samples, so they couldn't have been cross-contaminated at extraction stage; conceded that two types of DNA testing, PCR and RFLP, at three different labs failed to exclude Simpson as source of key blood evidence; said PCR testing was unreliable in criminal cases because of high chance of contamination.

TERENCE P. SPEED: statistics professor; testified that best laboratories can be plagued by errors; said that separating samples to be sent to different labs for testing doesn't fix problems that can occur during evidence collection; emphasized importance of incorporating laboratory error rates; acknowledged he didn't do analysis of facts in Simpson case and said he was testifying in the abstract.

MICHAEL BADEN: former New York coroner; disagreed with testimony by prosecution coroner, saying it is nearly impossible to determine number and size of assailants and number of weapons used in the killings; suggested attack took much longer to complete than prosecution believes; said prosecution witness may have erred in suggesting that Goldman suffered taunting-style cuts to neck before fatal slash to jugular; disagreed with theory that Ms. Simpson had foot placed on her back and had her throat cut while lying on ground with her head pulled back; said neither victim was prevented from screaming by their wounds; estimated that at least five and perhaps 15 minutes passed between the time Goldman's jugular vein was cut and he was stabbed in the chest; disputed that mark on Ms. Simpson's back was bruise from a shoe and instead attributed it to lividity, or settling of blood; defended autopsy work by medical examiner Irwin Golden, who did not find the marks; said he could not specify that Ms. Simpson was murdered at any specific time between 10:15 p.m. and 10:50 p.m. by condition of food in her stomach.

GILBERT AGUILAR: LAPD fingerprint specialist; compared all prints found at crime scene to known prints; colleagues determined on June 13, 1994, that none of 17 prints lifted from the crime scene was from Simpson; when Aguilar joined case, he reviewed work and determined it was accurate; went through all prints that were taken from crime scene and said nine were never matched; said those unmatched prints could have come from two of Ms. Simpson's sisters, her gardener, baby sitter, maid or even an Avon lady.

HENRY LEE: forensics consultant; said he is being reimbursed for expenses only, while about $50,000 that he would have been paid was donated to college and police agency; testified that bloody imprints found on envelope and piece of paper at crime scene didn't match sole pattern of type of shoes prosecution claims were worn by killer; said blood patterns on Goldman's jeans ``could be'' from shoe, but if they were, it was not a Bruno Magli shoe; said bloodstains show Goldman was slain while standing upright and struggling; said struggle was prolonged but couldn't say how long; said impressions in soil where Goldman's body was found should have been cast and analyzed by police investigators; gave jurors blood splatter demonstration, startling many when he smacked an ink blot to make a splash; said he examined pair of socks at police lab where he was treated rudely and denied access to adequate equipment; said socks had been contaminated by improper handling; said subsequent examination confirmed blood had seeped through all sides of socks, supporting theory that blood was planted; said he used PCR and RFLP in his laboratory; couldn't eliminate possibility that two police officers left some shoe prints at crime scene, but said he doubted it.

LAURA HART McKINNY: North Carolina screenwriter; said she met Fuhrman in 1985 when he asked about her computer in a cafe; said she taped their conversations and asked him to be as ``factual and realistic as possible'' as she looked for information for a story called ``Men Against Women'' about sexism in the LAPD; said she compiled 11 to 12 hours of tape over nearly a decade, said Fuhrman used the ``n-word'' more than 40 times in a ``very casual, ordinary'' manner while describing police work; said Fuhrman used the word as recently as 1988.
