The jury in the rape trial of Robert Jeffrey Lujan, son of Interior Secretary Manuel Lujan Jr., deliberated for eight hours yesterday after hearing closing arguments in which each side accused the other of relying on unbelievable fantasies.

Lujan, 28, is charged with breaking into the apartment of an Alexandria woman, threatening her with a shotgun and raping her after holding her captive for more than four hours.

The Alexandria Circuit Court jury, which was sent home about 10 p.m. last night and will resume deliberations today, heard from nearly three dozen witnesses during the three-day trial, but the outcome may hinge on the conflicting testimony of the woman and Lujan.

The 48-year-old woman said she awoke at 4:38 a.m. Nov. 11 to find Lujan sitting nude on her bed with a shotgun. The woman said she had never seen him before, and that after four hours of conversation he forced her to submit to sexual acts.

Lujan acknowledged that he and the woman were together that night, but he insisted that she had invited him to her apartment and initiated the sexual encounter when she answered the door in a robe and a low-cut nightgown.

Deputy Commonwealth's Attorney S. Randolph Sengel attacked Lujan's version of events, describing the defendant as a pathetic young man desperate for affection.

"The physical details of this rape are the most compelling testament to two things: the first is {the woman's} courage in the face of what happened, and the second is the absolute desperation and loneliness that led the defendant to do what he did," Sengel said during yesterday's closing arguments.

Sengel recalled testimony that Lujan had phoned several friends the night of the incident but they had refused to see him. He also cited the woman's testimony that when Lujan embraced her he threw her arms around his shoulders "as if to say, 'Please pay attention to me, love me.' "

Sengel said Lujan never verbally abused the woman because he was acting out a kind of fantasy and hoped to seduce her into having sex.

"He rationalizes his behavior by being a gentleman, being nice," Sengel told the jury.

Lujan has been in and out of legal trouble for a decade, serving time in prison for two minor felony drug convictions and joining several alcohol rehabilitation programs after seven convictions for driving while intoxicated.

Lujan testified Thursday that he and his girlfriend were having a fight at the time of the incident and that he drank seven or eight beers before he went to the woman's apartment.

Lujan's attorneys, Robert Stanley Powell and Joseph McCarthy, argued throughout the trial that the woman's story was crippled by inconsistencies. "It's her fantasy," Powell said at the close of the case. "We have a woman who has inexplicably intertwined fact and fiction, fact and fantasy."

Powell reminded the jury that the woman also had been drinking that night, first at a party in Arlington, then at a nightclub in Georgetown. He noted that the woman said she went to the nightclub with a man she had met at the party.

"She enjoys a social life, and her social life that evening was coming to a close" when she ran into Lujan on the elevator returning to his apartment after buying cigarettes from a basement vending machine, Powell said.

Powell said the woman wanted Lujan to drop by and wanted to look good when he arrived. Powell, displaying the woman's nightgown, said, "It's the kind of nightgown women wear when they want to be attractive, when they're expecting company."

Powell also asked the jury to ask themselves why Lujan never tried to hide his identity and why he told his sister an hour after he left the victim that he had spent the night with the woman.
