The father of a severely disabled teen who died after her home was ransacked by would-be burglars says his family has been utterly devastated by the ordeal.

Now, two weeks after tragedy struck, Allan Ali is speaking out, pleading for answers to the mysterious case.

"I would really like to say, whoever knows or whoever has any information, please come forward and help," Ali said in an exclusive interview with CTV. "Because I mean, these types of things, I hope they don't go unsolved."

Sixteen-year-old Cynara Ali was on the couch the morning of Feb. 19 when two masked men knocked on the door. Her 40-year-old mother Cindy opened the door but was quickly pushed aside as the men barged into the home, demanding she give them a "package."

Cindy told police one of the men led her around the house as he flung open cupboards, closets and drawers looking for something specific. The other suspect reportedly stayed with Cynara on the main floor.

The men, who never specified exactly what they were looking for, eventually said they had the wrong house and quickly fled the scene.

When Cindy went to check on her daughter, she found her unconscious and without a pulse. Cynara died in hospital the next day.

Ali says Cynara was the focus of his family's life and that he, his wife and three other daughters are having a hard time coping with the fact that she's gone.

"We've done everything, everything possible that we could do to make her very comfortable and be a part of our family," Ali told CTV outside his home Saturday. "She has been the centre of our family and she will continue to be the centre of our family because that's what our -- that's what we do.

"We love each other and we treat our kids the same, no matter if there's an indifference," he continued to say. "We never looked at it as an indifference. She was a beautiful child. And she'll, as I said, continue to be in our memories as a beautiful child."

Investigation continues

Police investigating the case say they too have many unanswered questions. Officers went door-to-door Saturday on Burrows Hall Boulevard, speaking with neighbours in hopes of uncovering fresh evidence and new leads.

Residents of the Malvern neighbourhood were asked if they had received any packages lately and what those packages contained, said Toronto Police Det. Sgt. Frank Skubic.

He wouldn't say if anyone reported seeing the two suspects in the area the day of the home invasion.

Among people that have been interviewed by police is a man who lives at a home that shares the same street address as the Ali family. Colin Pierre told CTV Toronto that there is no reason he would be targeted and that he has had no problems in the five years that he has been living at that location.

Pierre also said that he did not receive any packages lately.

"Nothing has showed up here, so I don't know what they're looking for or what it could have been," he said.

In the meantime, Cynara's cause of death is still being investigated. Once police have those results, the focus of their investigation could change. Skubic said he plans to meet with pathologists soon to review the evidence.

"Hopefully we'll be able to determine what caused this young lady to pass away," he said.

Ali says he is not sure whether his daughter died of natural causes or whether she was killed.

"I am not sure. That will be left up to the police to decide, to give that information. That, I have no comment on that one," he said.

All he is asking for is closure.

"She (Cindy) is not doing too well. My kids are not doing too well. I am not doing too well. I'm just trying to be brave for my family and trying to get this, to the bottom of this," Ali said. "I know the police, they have their work to do and I want to thank them too because they're doing a wonderful job."
