Heroic U of T student heartbroken after classmate killed in Scarborough house fire

When LoickMasunda's girlfriend saw smoke billowing from a Scarborough home Wednesday morning, the University of Toronto student leapt into action to help.

It was about 2:30 a.m. when Masunda raced over to the nearby home on Haida Court,near Ellesmere Road and Military Trail, where flames and smoke were pouring out of the back of the property. Two men rushed outside screaming for help, saying a woman was trapped inside.

On instinct, he says, he rushed over to the front window and broke it, pulling a woman out from inside.

"She was burnt, she was in pain, shocked," Masunda said. "I tried to calm her down and brought her to the paramedics."

Unbeknownst to him at the time, another woman was trapped upstairs.

This is a deep tragedy and we need to know what happened.- Toronto Fire Chief Matthew Pegg

He would later learn an 18-year-old woman was found dead, also a University of Toronto student at theschool's Scarborough campus. Three others managed to escape and were taken to hospital, one of whom jumped from a window onthe second floor but wasn't seriously hurt.

Paramedics took one woman in her 20swith serious injuries to a burn unit at Sunnybrook Health Sciences Centre.

But while he managed to rescue one person, Masunda says he wishes he could have done more.

"It's really heartbreaking, and my heart goes out to her family," he said, adding that he'd never been inside the home before and didn't know the layout. "It's really sad."

Toronto Fire Chief Matthew Peggsaid the smoke and flames were so intense that fire crews were not able to enter the home safely.

"This is a deep tragedy and we need to know what happened,"Pegg said Wednesday morning at the scene.

Investigators are still working to determine what caused the blaze at the home and whether working smoke alarms were present. Ontario's Office of the Fire Marshal and Toronto police have also been notified.

Pegg said investigators will be conducting an external scan of the scene before the work begins inside the home."The building is somewhat structurally unsafe at this point. We have to investigate the safety aspect of the building," he said.

"All we know is that there were four students living in the house or in the house at 2:30 in the morning when the fire started,"Toronto Fire Services Deputy ChiefJim Jessoptold reporters.

"We do not know the status of this specific building at this time."

The University of Toronto says it has contacted the students affected to support them and their family members, and any other members of the campus community who may be affected.
