TORONTO -- Jealousy drove a young New Orleans man to kill his Toronto girlfriend mere months after moving here to be with her, police alleged today.

A 23-year-old man was arrested after he walked into 53 Division police station at Yonge St. and Eglinton Ave. early Friday evening, said Det.-Sgt. Mike Barsky, of the Toronto Police homicide squad.

Investigators found the stangled body of a 19-year-old girl at the man's apartment, he said.

Barsky described the alleged motive as "jealousy," adding, "I'm just going to leave it as grey as that."

Investigators alleged the killing was pre-meditated and charged New Orleans resident Binh Nguyen with one count of first-degree murder.

The victim, whose name wasn't released at the request of her family, moved to Toronto from outside the province about two years ago. Though the couple's Huron St. apartment sits just south of the University of Toronto downtown campus, she was not a student. The victim worked in the food industry, Barsky said.

Her family wasn't given any signs that she was fearful for her safety prior to her death, Barsky said.

The victim and the accused had been in a relationship for just under a year. Nguyen only moved to Toronto about six months ago, Barsky said, adding he had visited the victim before making the move.

Nguyen, who didn't work or attend school since arriving in Toronto, presented himself as a calm and mild-mannered, Barsky said.

Because the pair mostly kept to themselves, "witnesses have been very difficult to identify and locate only because I don't know that there is any," Barsky said.

The couple lived on the second floor of a low-rise apartment building that is mostly occupied by students who keep to themselves, residents said today.

"It's a little unnerving, just not really knowing what's going on in your apartment building," said Kiersten Lappano, 22.
