D.C. corrections officials yesterday denied allegations by the lawyer of an inmate at the city's Lorton Reformatory that corrections officials did not give the inmate immediate medical attention when he was fatally stabbed Saturday night.

Robert Broadus, 33, was discovered on the floor in the recreation area with several stab wounds, corrections officials said.

His attorney, Robert Liotta, said that he was told by other inmates that Broadus was left bleeding on the floor for nearly two hours without medical treatment.

"That's ludicrous," Corrections Department spokesman Edward D. Sargent said yesterday.

Bernard L. Braxton, administrator of the maximum-security facility, said that his preliminary investigation revealed that a corrections officer who walked by that area at 7:55 p.m. "did not see anything outside of the ordinary."

At 8 p.m., Braxton said, a corrections officer discovered Broadus and she yelled for help. Within seven minutes, Broadus was in the infirmary of the prison, he said. Soon afterward he was taken to Dewitt Army Hospital at Fort Belvoir where he was pronounced dead about 90 minutes later. The Lorton complex is in southern Fairfax County.

Broadus' lawyer said that the victim's mother was not notified about the incident for 48 hours. But Braxton maintained yesterday that Broadus' mother was told about the stabbing by his sister Saturday night.

Broadus apparently called his sister from a prison phone shortly before the stabbing occurred, Braxton said.

After the incident, someone from the prison, perhaps an inmate, called to notify her. She called Broadus' mother, and they both went to Dewitt Hospital, he said.

"We left a prison number with the sister and told her to have his mother call," Braxton said. "When she didn't call, we sent the prison chaplain by the house."

Broadus had just won a $15,000 settlement from the District in a lawsuit alleging that he had been beaten by corrections officers, said Liotta.

"There is definitely no evidence that corrections officers were involved" in the stabbing, Braxton said.

Broadus was serving time at Lorton for weapons violations. He was previously an inmate at Lorton for convictions of second-degree murder, armed robbery, assault with a deadly weapon, carrying a pistol without a license and attempted robbery, Sargent said.

Sargent said that Broadus' slaying and another fatal stabbing in Lorton last weekend are being investigated by the FBI, which investigates all such incidents at Lorton.
