The Stafford County man charged in the killing of a Manassas youth last weekend apparently cut his throat with a disposable razor in his jail cell yesterday in what law enforcement sources called an attempt to take his own life.

Michael Carl George, 32, was treated at the Prince William County/Manassas Adult Detention Center by Manassas rescue personnel and taken to Prince William Hospital in Manassas. He was listed in stable condition last night.

Law enforcement sources said George used a jail-issued disposable razor while in his cell about 5 p.m. to cut himself severely, resulting in profuse bleeding.

Richard Kiekbusch, superintendent of the jail, declined to comment on the incident.

A hospital spokeswoman said George was admitted to the emergency room about 5:30 and transferred to a ward about 7:45 p.m. He was reported under guard last night.

Manassas City police said they were investigating, but gave no further details.

George, who has been held at the jail since early Monday, is charged with the killing of Alexander Eugene Sztanko, who disappeared June 16 after leaving his family's former home near the 15400 block of Cardinal Drive in the Woodbridge area to ride his dirt bike.

An autopsy determined that the youth had died of a single gunshot wound to the head. Court records show he had also been tortured in the groin area and thighs with an electronic stun gun.

George is scheduled for a court hearing on July 17.

George served 2 1/2 years in prison after pleading guilty in 1984 to involuntary manslaughter in the 1979 death of a 9-year-old boy.
