Georgetown hairdresser Raymond Louis Urgo cried twice yesterday as his defense was presented at his murder trial in Arlington. The first time was when Mary Lee Kingsley, a participant in a sex and drug party at his apartment last January, told the jury in a quavering voice how Urgo shot to death Ellen Dana Kisacky of Landover during the party.

He cried again as he listened to his tape-recorded call to Arlington police one minute after the shooting when he moaned: ". . . life is ruined . . . life is ruined. Oh Dana, Dana, Dana."

The defense called Miss Kingsley to testify and played the tape to butress Urgo's contention that his shooting of Miss Kisacky was an accident and that he had not malice toward her.

After Urgo's attorneys played the tape, the defense rested its case in the week-long trial. Prosecutors called three rebuttal witnesses and then Arlington Circuit Court Judge Charles S. Russell ordered the jury sequestered over night because of the large amount of publicity about the case. They will begin their deliberations today, Russell said.

Part of the reason for the wide coverage of the trial stems from the profusion of testimony about the unusual sexual activities that Urgo and his female companions participated in the night of Miss Kisacky's death, including inferences to the erotic use of guns, chains and handcuss, and Urgo's involvement at various times with heroin, cocaine, quaaludes and marijuana.

To illustrate the drug use, Kingsley testified that after she and Urgo "did quaaludes" one day before the Jan. 8 killing, they were playing karate with each other, and she dislocated one of his fingers.

Kingsley, 24, of 1314 N. Courthouse Rd., Arlington, began crying when she testified concerning how Kisacky was shot by Urgo through the mouth with a .357 magnum revolver.

Kingsley said she had come to Urgo's apartment on Jan. 8 to get a quaalude, a barbiturate-type drug, from him because she was depressed. Later she undressed, entered Urgo's bedroom where Kisacky and Monique Tyson, of Luxembourg, were lying nude on the bed. In earlier testimony, Urgo said he, Kisacky and Tyson had been engaging in sex earlier during the evening.

Kingsly testified Tyson began kissing her. She saw Urgo approach the bed, where the three women were lying side by side, and load his revolver with bullets, Miss Kingsley said.

"Monique again turned her attentions to myself," Kingsley testified. "Something caught my eye and I looked up and saw Ray standing at the end of the bed.

"I made some comment like, 'Ray, what are you doing?'" Kingsley testified. "Monique turned and said, 'Oh, don't pay any attention to him. He's crazy.'"

Dana was smiling, Kingsley said. She turned back to Tyson. Then she heard a shot, "like a muffled pop."

"I looked at the wall because I expected to see some sort of hole in the wall," Kingsley testified, her voice beginning to quaver. "Then I looked at Ray. He was sort of stricken . . . frozen . . . he was absolutely ashen."

THen she said she looked at Kisacky.

"She had blood coming out of her mouth. She was white and her eyes were all bluish," Kingsley testified a broken voice. She choked for a second and began crying.

"Monique started screaming, 'oh my Goh! What's happened?"

Urgo immediately called police, Kingsley said. Then he returned to bed.

"He was lokking at her body and he said, 'Dana, I know you can't hear me now, but please forgive me. It was an accident," Kingsley said, having regained her composure. "He said it in such a broken-spirited way. It was a hopeless tone."

The tape of Urgo's phone call to police after the shooting was also introduced to support the accident claim. Jody Boraski, a police communications officer who received the call, said Yrgo did not know the conversation was recorded. Incoming calls are routinely recorded, Boraski said.

In the conversation, Urgo first asked if he was talking to police. Then he asked that a patrol car be sent to his Arlington Towers apartment, located at 1121 Arlington Blvd. When Boraski asked why, Urgo replied, "There's been a shooting. Someone is dead. A person is dead."

Boraski asked if it was suicide, "No, it was an accident," Urgo replied.

In the background, women's voices could be heard. In the courtroom, Urgo began wiping his eyes with a tissue.

"Who's there with you?" Boraski asked in the conversation the night of the shooting.

"Her name is," Urgo paused and signed. "Ellen Dana Kisackey . . . she lives with her parents, but she stays with me a lot of time."

"Where is she now?" Boraski asked. "She's dead, in my bed . . . please . . . Please . . . life is ruined . . . life is ruined. Oh, Dana Dana Dana," Urgo moaned while Boraski had put him on hold.

"I have to hang up, "Urgo then said and he did.
