An inmate at the Prince William County jail told police that Michael Carl George said he killed a 15-year-old Woodbridge boy and two other youths, sources said yesterday.

George, 33, is being held at the jail in connection with the slaying of Alexander Sztanko, who was found dead on June 17 of a gunshot wound in the head.

Documents filed Wednesday in Circuit Court show that Commonwealth's Attorney Paul B. Ebert intends to call at least one witness at George's trial who will testify that George said he killed Sztanko, 8-year-old Larry Perry, of Dumfries, and an unidentified third person. George served prison time for involuntary manslaughter in Larry's death.

The court records say that "one Commonwealth's witness has received a reduction in sentence without objection by the Commonwealth." A second potential witness, who was facing revocation of his probation on an unrelated charge, has been allowed to remain on probation, Ebert said.

Ebert declined to say whether either of the men is the source of George's alleged statements about the slayings. He would not say whether prosecutors made a deal with the men in exchange for their testimony against George.

George's attorney, Lon Farris, said the documents indicate that the potential witnesses against his client are in jail and may have been in contact with George since he was jailed June 18. The records clearly show that there have been "deals of some sort" offered to the witnesses, Farris said.

The documents also state that the prosecution has the name of a "juvenile detainee who heard another individual was with Michael George at the time of Alex Sztanko's death." Police said yesterday that no other suspects are being sought in connection with the Sztanko case.

County police spokeswoman Kim D. Chinn confirmed yesterday that the alleged statement linking George to the three slayings included a description by George of how he picked up a third youth and later killed him. Sources said George did not identify the boy.

Chinn said police have attempted to match the statements George made to unsolved local killings, but they have been unable to identify a victim.

Even if a third victim cannot be identified, George's statements involving such a slaying still can be presented in his Dec. 3 trial, Ebert said.

"He is not being tried for a third murder. If he wants to fabricate a statement, he can do that," Ebert said. "If he wants to say he killed the pope, it would be germane to the Commonwealth and it would go as to whether or not he was a danger to society, whether we can verify the truth of it or not."
