The 16-year-old suspect in the stabbing deaths of three young Anne Arundel County girls was take by his father to the U.S. Naval Academy Hospital at Annapolis the afternoon after the murders, reportedly to be treated for a knife wound.

A hospital spokesman confirmed yesterday that Stuart L. Kreiner whose father is retired from the Navy, was treated at about 4 p.m. Monday. The spokesman refused to discuss the nature of his injury, however, saying that hospital records have been subpoenaed by county prosecutors.

Kreiner, whose home on Cross Crrek Drive in the Southgate community is less than a block from the homes of the three slain girls, has been charged with three counts of first degree murder in the case.

The fully clothed bodies of Deborah Ann Hogan, 10, her sister, Theresa, 8, and Ann Brzeskiewez, 8, were found shortly after 8 Monday morning lying face down in a muddy streamin the woods a few hundred yards from their homes.

Kreiner was arrested by Anne Arundel County police at midday Wednesday, after his parents had retained an attorney and notified police that they suspected their son of the crime.

The youth was limping when police picked him up at his home according to sources familiar with the case. The knife wound in his right leg had reportedly been closed with several stitches Monday afternoon.

Kreiner was picked up at the usual time on Monday morning by the carpool that takes him to Martin Spauiding High School, some of the youth's neighbors reported yesterday.

However School Officials, who have repeatedly refused any comment on the case, would not say whether the youth was treated for any injury by the school's medical personnel.

Sources close to the investigation said yesterday that Kreiner, who is being held in an isolation cell at the Anne Arundel County Detention Center, has consistently refused to talk to police. He won't even say as much as "how are you," one source said.

Kreiner, the son of former state labor leader Edward T. Kreiner and his wife Leona, is being held without bond at the request of his own defense attorney, J. Edward Davis.

Davis refused comment on the case yesterday, except to say that he expects to petition the state courts early next week requesting a psychiatric examination for his client.

The defense attorney would not say, however, whether the Kreiners had retained a psychiatrist to examine their son. The family apparently left their home before Stuart's arrest Wednesday, and no one has answered their telephone since that time.

The three murdered girls were buried Thursday at the Glen Burnie, not far from their homes.

Deputy States Attorney David Cuttler said yesterday afternoon that the case against Kreiner would be presented to an Anne Arundel County grand jury on Monday and that he expects the grand jury to return indictments by Monday afternoon.
