A week after the deadly train derailment in Lac-Megantic, Que., frustration is growing among some evacuees who say they鈥檙e struggling to obtain vital information about the town鈥檚 recovery efforts.

Patrice Laframboise, a local doctor, confronted Mayor Colette Roy-Laroche after a media briefing Friday, saying his family has been left in the dark.

鈥淲e are not able to find out where the information is,鈥� Laframboise said as he grasped the mayor鈥檚 shoulder. 鈥淲e have no phones, no clothing, nothing.鈥�

Laframboise鈥檚 home is in the red zone, the area hardest hit by the train tanker explosion. He said the house is still standing, but no one can tell him how long he鈥檒l have to wait to see it.

鈥淚 need this information,鈥� he told reporters. 鈥淒o I find another house for a couple of months and reintegrate later? For now it鈥檚 difficult to continue my life. We鈥檙e in survival mode.

鈥淲e still have some patience but when you don鈥檛 have information the impatience starts to come in.鈥�

Many of the 200 residents who still can鈥檛 enter their homes are just as frustrated. Some of them are sleeping on cots at the emergency shelter, while others are staying with family and friends. It could be weeks 鈥� or months 鈥� before everyone will be allowed to go home.

鈥淭he town tries, but we are getting all our updates from the television,鈥� Claude Robert said.

One woman interrupted a police news conference Friday, yelling: 鈥淪top saying nothing and start doing something! We need to get home.鈥�

Many residents climbed onto rooftops near the downtown core in hopes of catching a glimpse of their homes and businesses, but police immediately threatened to charge them with trespassing.

Others have ripped holes in barriers erected around the red zone in an effort to sneak a peek.

鈥淲e wanted to come see it,鈥� said one woman. 鈥淲e needed to.鈥�

The town says it鈥檚 doing its best to balance the needs of displaced residents with those of investigators. It also noted that daily updates are posted on the municipality鈥檚 website and at the emergency shelter.
