Mistrial: The trial of a Lanham man charged with first-degree felony murder and other crimes in the robbery and fatal shooting of a Mitchellville physician ended in a mistrial yesterday.

Christopher Kargbo, 20, was on trial in the slaying of Thomas A. Gay, 61, who was shot to death in the driveway of his home July 22, 2003. Jurors deliberated about eight hours over two days before announcing yesterday afternoon that they were deadlocked.

Circuit Court Judge Thomas P. Smith declared a mistrial. Assistant State's Attorney Laura J. Gwinn, chief of the violent crimes unit, said jurors were split 9 to 3 in favor of conviction. Gwinn said Kargbo, who remains incarcerated, will be retried.

In March, a jury convicted Arthur Royal, 20, of first-degree felony murder and other crimes in connection with the shooting.

Arrest in old case: A Baltimore murder suspect who had been wanted by police for nearly 30 years has been arrested in Boston, police said yesterday.

Michael Hughes, 58, is charged with killing a Baltimore police employee in a Christmas Eve shooting in 1974. Hughes was charged shortly after the killing with first-degree murder, and police have been seeking him ever since.

He was arrested Sunday after he was accused of slashing a man with a small knife on a bus, police said.
