On Thursday, a Toronto jury will resume deliberating the fate of a teenaged girl accused of plotting the murder of 14-year-old Stefanie Rengel, someone the defendant had never met.

"They'll presumably go to a hotel, and they'll resume their deliberations at 10 (a.m.)," defence lawyer Marshall Sack told reporters outside the courthouse about 7 p.m. on Wednesday.

He wouldn't speculate on how long it would take: "It could be forever ... We just never know. And you can't read anything into how long or how short a jury takes. It takes as long as it takes."

Sack described his now-17-year-old client as "nervous and hopeful -- as are her family."

Justice Ian Nordheimer charged the jury in the morning, a legal process where the jury is instructed on the applicable law. The jury members began their deliberations shortly after 12:30 p.m.

Over the last several weeks, the jury heard evidence that the  defendant was bitterly jealous of Rengel and pressured her then-boyfriend, who had known Stefanie, to kill the younger girl.

The jury in the first-degree murder trial was given several volumes of online chats between the accused and the male where the teen threatens to withhold sex and break up with him if he didn't carry out her wishes.

Rengel was stabbed to death on New Year's Day in 2008 steps away from her home in East York. A 19-year-old man who can only be identified as D.B. is also facing a first-degree murder charge in her death. His trial will begin later this year.

The man and the accused, known publicly as M.T., can not be properly identified because they were both minors at the time the murder took place.

The jury sat through closing arguments on Monday and Tuesday, listening to Crown and defence lawyers tell their side of a the sordid story.

The defence, which did not call any witnesses or present any evidence during the trial, took six hours to argue before the jury that M.T. was not serious when she suggested to D.B. that he kill Rengel.

"I tried my best," Sack said.

He hoped the jury would look in detail at the instant messages, other online communications and cellphone records -- and look at the context.
