Michael Charles Satcher, charged with attacking two joggers last weekend on an Arlington recreation trail, has the same rare combination of blood characteristics as the person who killed Anne Elizabeth Borghesani five months ago, prosecutors disclosed yesterday.

Arlington prosecutors said the match strengthens the possibility that Satcher was involved in the March 31 slaying of Borghesani, 23, of Rosslyn, on another nearby bike path.

"Mr. Satcher is a suspect in the Borghesani homicide case," Deputy Commonwealth's Attorney Richard E. Trodden said in court yesterday.

Scientists at the Northern Virginia Forensic Laboratory in Fairfax, examining characteristics in blood and other bodily fluids, determined that both Satcher and the person who brutally stabbed Borghesani to death have a combination of blood factors shared by only seven people in 100.

Police took hair, saliva and blood samples from Satcher for testing after his arrest on Saturday. They were compared with samples taken from Borghesani's body and the site where she was found.

The blood test results were the basis for the county's successful court motion yesterday morning to have Satcher's bond revoked. Until yesterday, the prosecution had taken care to make no direct links between Satcher and Borghesani's death.

"Since we learned that the defendant is of the same blood type as the man who assaulted Miss Borghesani . . . we argue that he poses a severe threat to the community," Trodden said.

Satcher denied involvement in the Borghesani killing when interrogated by police, Trodden said. His attorney, John C. Youngs, said that Satcher also maintains that he is innocent of the bike path assaults last Saturday, with which he has been charged.

Prosecutors said Satcher faces a maximum penalty of 60 years in prison if convicted of three felony charges stemming from Saturday's attacks.

On Wednesday, motions were made by the defense to have Satcher's $40,000 bond lowered, and by the prosecution to have bond raised. Both were denied.

But yesterday, agreeing with Trodden's argument that the new evidence raised the level of risk to the community if Satcher were released, Arlington General District Court Judge Francis E. Thomas revoked Satcher's bond.

Youngs appealed the judge's ruling later in the day, but his motion to have the bond restored was denied. Youngs said he is considering appealing the decision to the Virginia State Court of Appeals.

Satcher, 22, was arrested about noon on Saturday and charged with attacking two women in South Arlington on the Washington & Old Dominion Trail, a biking and jogging path.

Police allege that at the time of his arrest, Satcher had a T-shirt in his hand, under which he had concealed a knife with the blade extended.

At yesterday's bond appeal hearing before Circuit Court Judge Benjamin N. A. Kendrick, Youngs argued that revocation of his client's bond was "unfair and inappropriate."

"He has two prior drug felony convictions. The best indicator of violence is whether a person has been involved in crimes of violence."

"There is no homicide warrant," Youngs said, alleging that the prosectution has penalized Satcher for the Borghesani killing, a crime in which he has not been charged.

"The commonwealth can't try to slide under the door with what they can't get by opening it. If they have evidence, they should charge him with that crime," Youngs said.

Arthur Karp of the Commonwealth's Attorney Office said the judge must balance "the likelihood that {Satcher} is the person we're looking for against the danger he poses to the community.

"If he is an extreme danger, even if there is a relatively little likelihood that he has committed the crime, we would argue for his remaining in custody . . . . Until we get an absolute determination that he is not the person {who killed Borghesani}, he ought to be in jail."

Prosecutors left open the question of whether Satcher will be charged in the Borghesani slaying, pending DNA test results on bodily fluid samples from the state crime lab in Norfolk. An Arlington police spokesman said it could be several weeks before those test results arrive.

"This case," Karp said, "will hinge on the result of those DNA tests. It's about as positive as anything you can get in the real world."
