NY- An accused stalker kept a cybershrine to broadcasting beauty Monica Crowley on his computer and confessed in creepy e-mails that he was dangerously obsessed with her.

"I think of you, Monica, constantly," homeless artist Ronald Martin, 41, gushed in one of the bizarre messages introduced as evidence at his trial yesterday.

Some of the e-mails were composed on a laptop Martin stashed beneath the floorboards of a dark lair, an abandoned waterfront building in Manhattan where he was squatting - a desolate, decrepit pier with a view of the Statue of Liberty.

The hideout was decorated with the painted slogan, "I Love Monica," and police found a copy of a book Crowley wrote about her one-time boss, former President Richard Nixon.

The laptop screen saver was a poster of the petite blond wearing headphones, and cops seized a cache of other photos off the hard drive, police said.

But the flood of e-mails to Crowley - who now works for WABC-AM radio and MSNBC - was the most disturbing.

"I stopped counting at 463," Detective Joseph Cornetta, who arrested Martin, told a Manhattan Supreme Court jury.

On cross-examination, Cornetta confirmed that most of those were lost, swiped off his desk one night, but he read aloud three that were saved.

"I like your new haircut, the way the short lock on the right fell be for [sic] your cheek," Martin wrote on Jan. 24, 2004.

"The wonderful smile you provide in your portraits not only make me smile, but giggle in childish glee. My mind has become so preoccupied. Overrun by my indulgence of your personality."

Days later, he sent another missive, admitting he thought of Crowley every time he passed a blond and was haunted by her voice on radio and television.

"She's on Morning, Noon and Night: this woman knows exactly what she is doing to me," he wrote. "I thought I had it all under control."

He became fixated on a comment she made likening the New York City blackout to the horror flick "Dawn of the Dead."

"It kept repeating in my head, 'Dawn of the Dead, where is that coming from?'" he wrote.

He continued to send the comely commentator e-mails until a few days before his July 2004 arrest - even penning one just days after he accosted her on a midtown subway platform, forcing her to scream for help.

"I miss you," it began. "You are the prettiest, and have the prettiest voice I have ever heard." The e-mail was signed, "have fun, hurry back."

Martin, who is charged with misdemeanor stalking and harassment, claims he was trying to befriend Crowley, 37, and that she never told him to stop.

Told outside court that a man accused of stalking rocker Sheryl Crow was acquitted in the same courthouse two years ago, he said, "I hope that happens to me."

Before the day's testimony began, Martin's lawyer Stuart Singer asked the judge to allow a psychiatric defense.

But Martin, who has been in and out of mental hospitals for a year and a half, shook his head. "I do not want that, judge," he protested, before the judge shot down Singer's motion.

The trial began Tuesday with dramatic testimony from Crowley, who described how Martin would camp outside her office with a rose in hand and beg to speak with her.

She said she was "scared to death." She eventually called police, who sent Martin a warning e-mail he ignored. He was arrested in July 2004 after he allegedly grabbed her in the subway.

Prosecutors also revealed Crowley wasn't Martin's first alleged victim. Before he pursued her, he stalked an Indiana professor until she took out a restraining order, sources said.
