Weston

WASHINGTON (CNN) -- Accused killer Russell Weston Jr. remained hospitalized in stable condition Wednesday, according to doctors who said they were "guardedly optimistic" he would recover from bullet wounds received in a gun battle that left two Capitol Police officers dead.

His vital signs are sufficient to ensure that survival is "probable," Dr. Ronald David of D.C. General Hospital told reporters.

Dr. Kenneth Alleyne said Weston's broken right arm and left thigh bone had been temporarily stabilized during a surgical procedure Tuesday.

At a news briefing outside the hospital, doctors said Weston was able to interact with them but would go no further in describing his conversations with them.

Hospital officials said Weston has had several visitors, including his public defender, A.J. Kramer. They would not identify the other visitors except to say that Weston's family had not been to the hospital.

Weston, a diagnosed paranoid schizophrenic who has been formally charged with murder, is under heavy police guard at the hospital. The FBI said in court documents made available Tuesday that Weston's parents said he had an irrational fear of government that had become an "overriding feature" of his life.
