Following the lead of more than two dozen states, 39 New Jersey lawmakers are supporting a proposal that would require sex offenders to submit blood samples for DNA profiling. The measure would force convicted sex offenders to give samples of their blood to the state police. The information would then be entered into a national DNA database used by local, state and federal law enforcement agencies for criminal investigations, much as electronic images of fingerprints are used today.

A new "DNA fingerprinting" process has matched bloodstains from serial- murder suspect Steven B. Pennell's van with the blood of one of his alleged victims, a Maryland scientist testified yesterday. Jurors got a crash course in molecular biology during testimony by Robin Cotton, research manager at Cellmark Diagnostics of Germantown, Md., as Pennell's trial entered its sixth week in Delaware Superior Court. Cotton explained how the relatively untried DNA fingerprinting process, developed about a year ago, was used to match a bloody rug taken from Pennell's van with the blood of Catherine A. DiMauro.

The Maryland laboratory chosen to do DNA testing on the undergarments of a 1981 rape-murder victim may not have the proper technology to determine whether semen stains on the clothing belong to Nicholas Yarris, the man sentenced to death for the crime, according to a forensic scientist familiar with the case. Given the age and condition of the semen sample, forensic scientist Edward Blake said, successful analysis is far more likely using a technique called polymerase chain reaction (PCR)

Serial-murder suspect Steven B. Pennell will go on trial in Delaware Superior Court today to face charges that he kidnapped, mutilated and murdered three Delaware women between 1987 and 1988. Authorities expect the two- to three-month trial of Pennell, a 31-year-old electrician and father of two from Glasgow, Del., to be one of the longest and most complex in Delaware history. State Deputy Attorneys General Kathleen Jennings and Peter Letang plan to question 100 witnesses.

A Maryland laboratory chosen to do DNA testing in a Delaware County rape- murder case has failed to determine whether semen stains on the victim's clothing belong to the man sentenced to death row for the killing. Nicholas Yarris, 31, was convicted of the December 1981 murder of Linda May Craig, a 32-year-old mother of three. Yarris was granted court approval in 1989 to have Craig's undergarments tested at Cellmark Diagnostics of Germantown, Md. Cellmark conducted "DNA fingerprinting," a process that compares a suspect's basic genetic material - DNA - with the genetic material in blood or semen that may be found at crime scenes.

There was a day when a criminal could feel fairly safe in leaving the scene of the crime by simply wiping away telltale fingerprints. But that was before the age of high-tech crime detection. Pretty soon, even the tiniest bit of a crook's body will be enough to link him or her to the crime. That means blood, sweat and tears, semen, a scrape of skin, a single hair - anything with a genetic fingerprint on it. Civil libertarians and defense lawyers are worried. But police and prosecutors are looking ahead to an easier time bringing the guilty to justice - not to mention conclusively clearing the innocent.

DNA fingerprinting, generally used to cement the identification of the guilty, may prove to be the salvation of a Chester man accused of raping a blind woman. Harold Belgrave, 29, of the 2200 block of Crosby Street, was released late Thursday from Delaware County Prison after the District Attorney's Office received genetic test results in the case. "The DNA fingerprinting indicates it was not the defendant's semen found on the victim's blue robe," District Attorney William H. Ryan Jr. said yesterday.

Two months ago, two prominent scientists who have been vocal opponents in the battle over the use of DNA testing in court jointly announced in a respected scientific journal that "the DNA fingerprinting wars are over. " But no peace yet has been declared in the courtroom of Judge Lance Ito, who, beginning tomorrow, will preside over what could be a long and hard- fought hearing over DNA tests in the O.J. Simpson trial. Confronted with conflicting appellate court decisions, teams of clashing experts and massive motions detailing the eye-glazing technicalities, Ito must decide whether the results of DNA tests on blood taken from the crime scene and Simpson's estate and car can be presented to the jury.

DNA fingerprinting techniques are accurate and should be accepted as evidence in court, U.S. geneticists said yesterday. They pointed in particular to the O.J. Simpson double-murder trial, in which court debates about the admissibility of DNA evidence have made daily headlines. The latest procedures and standards are reliable and, if anything, give an advantage to defendants, Eric Lander of the Whitehead Institute for Biomedical Research in Cambridge, Mass., and Bruce Budowle of the Federal Bureau of Investigation wrote in today's issue of the journal Nature.

INFANT MONITORS Watch out, parents - those infant monitors that let you listen to your kids from across the house may be broadcasting your most private affairs throughout the neighborhood. Radio-scanner enthusiasts with reasonably good roof antennas can pick up the signals up to half a mile away. And Monitoring Times, a magazine for scanner buffs, recently published the monitors' frequencies. DIET TIPS If you have an overactive sweet tooth, keep up your intake of chromium.
