Accused murderer Alicia Murphy says she wasn't anywhere near the place where police and Crown prosecutors believes she beat, then drowned Evangeline Billy early on June 23, 2008.

The 29-year-old woman is accused of killing Billy during a struggle after she tried to rob the deceased Carmacks woman.

Murphy took the stand in her own defence Tuesday and today during her trial for second-degree murder, currently being heard in Yukon Supreme Court.

According to the timeline laid out in the evidence presented by prosecutor Noel Sinclair, Murphy could have killed Billy sometime between midnight and 2:30 a.m. that Sunday.

At all other times, her whereabouts have been accounted for by witnesses who have testified during the trial, which began last week.

But yesterday, Murphy gave the court her alibi for those hours.

At around midnight, she and two female friends stopped at the Skyline Apartments in Riverdale to buy crack, Murphy testified.

She went inside with the money, she said, while the other women waited in the truck.

Murphy said she bought six crack rocks for $100. She spent about an hour at the dealer's home, during which time she smoked four of the rocks.

One of the two women who were waiting outside for her testified last week that they became tired of waiting after about 45 minutes and went back to the party without Murphy.

Murphy told the court she remembered the time when she left because she asked the dealer and he told her it was 1:30 in the morning.

The dealer, who went by the name Chucka, will not testify at Murphy's trial. He killed himself on July 28 of this year, the jury and Justice Ron Veale heard today.

Crown prosecutor Noel Sinclair spent much of this morning's cross-examination asking Murphy about her drug use.

She told him she was addicted to both crack and alcohol, but said she was in control of her addiction and only used when she wanted to.

Later in the questioning, she said she would smoke crack whenever it was available, sometimes going for days without stopping.

From the dealer's apartment, Murphy said, she she went home and smoked the rest of the crack by herself.

"I figured seeing as I'd started smoking (the drugs), I might as well finish,” Murphy said when asked why she didn't deliver the crack to the friend who had paid for it.

She said she felt bad about smoking the drugs all by herself once she got home, and made up a story about where they went.

After finishing the crack, she called her sister's house, where her friends were partying, and told them she'd been ripped off for the drug money.

She called a cab and returned to her sister's place on Jeckell Street, arriving at around 3 a.m., she told the court.

There, the woman who had paid for all the drugs and alcohol Murphy consumed that night gave her cab money.

Murphy was unemployed for some time before the weekend in question, she said.

She was living on social assistance and her family's generosity, she told the court, and would get friends and acquaintances to buy her drinks and drugs.

Murphy said she stayed at the party until 4 a.m., and left because her sister was teasing and bullying her. She took with her a full 15-pack of beer.

Murphy's sister and friend Warren Edzerza both testified last week they were mad at Murphy for taking the beer and for going through the generous woman's purse.

Murphy said she asked Edzerza to come back to her place, but he was mad at her and refused.

She went home alone but soon called another friend because "I didn't want to sit by myself, drink beer by myself,” Murphy testified.

She called for a cab at 5 a.m. and headed out again.

At the friend's house in the industrial area, she continued drinking and smoking crack for a few hours, then headed downtown, this time with her friend Rae Lynne Gartner.

They were going to buy more crack, Murphy said, but decided to go to the 98 Hotel instead.

They spent the rest of the day there, drinking, and occasionally going down to the river to smoke crack.

Both Gartner and Murphy's sister Tanya have testified Murphy confessed to beating Billy and accidentally killing, then propping up her body to make it look as if she had been raped.

She allegedly made the comments on the afternoon of June 23. Each woman said she heard the confession when she was alone with Murphy.

Gartner called Whitehorse RCMP that night. After hearing her story, officers went to the sister's house, where they were told of a similar confession.

Murphy was arrested at around 1 a.m. on the Monday.

The accused woman said today that when the police knocked on her door that morning, she was just starting to fall asleep after being awake for the entire weekend.
