The Crown has wrapped up its case in the first-degree murder trial of a teen accused of pressuring her boyfriend to kill a girl she had never even met.

The jury will learn Friday if the defence for the accused, who can only be identified as M.T., will call any evidence.

One of the finals acts by Crown prosecutor Robin Flumerfelt was to tell the jury that a person who found mortally wounded Stefanie Rengel on New Year's Day 2009 made a call to 911 at 6:12 p.m.

Cellphone records show that D.B., the boyfriend of M.T. and someone who will eventually face trial on a first-degree murder charge himself, had called the cellphone of victim Stefanie Rengel about five minutes earlier.

Ian Rengel -- younger brother of Stefanie, who was only 14 when she died -- has testified that she took a call.

"'I'll be back in two seconds,'" she told him, he testified.

Gavin Shoebottom found Stefanie staggering along the street after someone had stabbed her six times.

She told him, "It hurts so much, it hurts so much," he testified.

Shoebottom made the call to 911. When paramedics arrived, she had lost consciousness.

Neither M.T. nor D.B. can be named under provisions of the Youth Criminal Justice Act.

Although D.B. is accused of stabbing Stefanie, M.T. is accused of "counselling and encouraging" him into committing the act, in part by denying him any sexual activity with her unless he killed her rival.

Much of the Crown's case hinges on cellphone and text message records. The jury has records from Sept. 1, 2007 to Jan. 1, 2008. The key dates, however are Oct. 20, 2007, Dec. 31, 2007 and Jan. 1, 2008 -- the day of the murder.

Oct. 20 is a key day as D.B. went to Stefanie's house to tell her that M.T. had asked him to kill her, according to testimony from Patricia Hung, Stefanie's mother and a Toronto police officer.

On Oct. 21, M.T. told D.B. "I want her dead LOL ... If it takes more than a week then we're just gonna be friends."

On Dec. 31, a neighbour spotted D.B. lurking near Stefanie's East York home, looking suspicious and constantly using a cellphone.

Justice Ian Nordheimer gave the jury most of Thursday afternoon to study the hundreds of pages of cellphone and text message records. The records are for the cellphones of M.T., D.B. and Stefanie.

The Crown has also submitted video of an interview police conducted with M.T. about 12 hours after Stefanie's murder.

"I asked him what he did. He said he stabbed her," the accused told Det. Steve Ryan.

"Did you feel any emotion?" he asked her.

"I was surprised he would do that. I didn't want her dead. It was a joke," she said.

After the stabbing, the girl invited D.B. to her home. Asked why she didn't call 911 or tell her parents about what D.B. had done, M.T. said, "I don't know."
