WASHINGTON, May 6 - A sharply critical independent audit found Friday that Virginia's nationally recognized central crime laboratory had botched DNA tests in a leading capital murder case. The findings prompted Gov. Mark R. Warner to order a review of the lab's handling of testing in 150 other cases.
The auditors recommended that the governor restrict the work of the lab's chief DNA scientist, Jeffrey D. Ban; review 40 cases Mr. Ban has handled in recent years as well as sample totaling 110 other lab cases; and develop procedures to insulate the lab from any outside political pressures.
Experts said the findings could lead to a re-examination of scores of past prosecutions, including those involving some of the nearly two dozen inmates on Virginia's death row, and might also throw into turmoil many current prosecutions in which the lab's work helped identify or rule out suspects.

Governor Warner called for the independent audit of the lab last fall in response to the case of Mr. Washington, a retarded man who came within days of execution for a rape and killing before DNA evidence, though not resolving the case, did raise doubts about his guilt.

Although retesting of the evidence in 2000 led to the pardon of Earl Washington Jr., the lab's leading DNA analyst made several mistakes, including prematurely excluding suspects when he should have ruled the DNA sample inconclusive, the audit concluded.
