GI CLAIMS HE WAS CRAZY IN EVIL COLO. SEX SLAYING

She was a "good girl" and he was a soldier who seemed destined to be together. Then it all went wrong.
Now, Robert Markio, 23, a veteran of combat in Iraq is on trial for raping and murdering Judlianna "Judi" Lawrence, 19, of Fort Collins, Colorado in 2008. He claims he's insane.
Cops say the burly Markio met "Judi" through MySpace and the pair were soon having sex.

Loving daughter

An informant fingered the soldier, who boasted on his MySpace page: "I'm becomeing (sic) a cold hearted killer and can kill without mercy or reason."
 Markio's yellow Jeep was spotted near the area where Judi's body was found. When questioned by detectives he led them to the body he'd stashed in a wooded area near Colorado Springs' Broadmoor area.
The sinister GI then told cops he'd had sex with Judi but then they argued--and he slit the young beauty's throat.
Her mother Aekyung Lawrence, discovered the
clandestine affair earlier.
"She's such a good girl," Aekyung Lawrence said. "She never dated. She doesn't even drive."
The online relationship had spanned several months, according to the dates on the e-mails. Lawrence was listed as a "friend" on Marko's MySpace page.
Marko's MySpace page showed photos of him in Iraq, holding weapons. On his profile, he said, Under a section marked "Who I'd like to meet," Marko's page says, "One day i would like to meet death."
Marko was a mortarman with the 4th Brigade Combat Team of the 4th Infantry Division. He served in Iraq from January 2007 to February 2008.Marko has pleaded not guilty by reason of insanity.
