Homicide investigators in British Columbia have released a surveillance video showing two men who may have information about the slaying of a Simon Fraser University student.

Maple Batalia was gunned down in a Surrey parking garage after a late-night study session in September.

The 19-year-old nursing student and aspiring actress was rushed to hospital, but succumbed to her injuries.

Police quickly determined she had no ties to gangs or drugs, saying Batalia had no "questionable lifestyle" factors that contributed to her death.

Investigators now want to identify two men seen entering the nearby Simon Fraser University campus shortly before the time Batalia was killed.

Sgt. Jennifer Pound of the Integrated Homicide Investigation Team said the men are not considered suspects.

But she said they should feel an obligation to make contact with police.

"This girl had her whole life ahead of her. You are obligated, you should feel obligated to come forward and speak to investigators," Pound said Thursday, appealing to the men to contact police.

In the months that have followed Batalia's slaying, police have also found a White Dodge Charger that they believe is tied to the murder.

"We believe that the people that were involved that had something to do with Maple's homicide were connected to that Dodge Charger," said Pound.

Meanwhile, the slain woman's family is finding it tough to be without their daughter during the holidays.

Harkirat Batalia said his daughter used to enjoy decorating the house at this time of year.

But now they are forced to confront the reality that she is no longer around.

"It's very painful to not see her any more," he told CTV British Columbia on Thursday.

In addition to being a student, Batalia was a model and actress who had once played a small role in one of the movies based on the "Diary of a Wimpy Kid" book series.
