The home which was the scene of a mass murder two years ago has gone up for sale.

News of the sale of the Dalhousie home came as a shock to the families and friends of the victims.

Just over two years ago, Amber Bowerman – a tenant in the home – was killed in a surprise attack by one of the homeowners. Joshua Lall then went on to kill his wife and two of his three children before killing himself.

"It's the Dalhousie murder house and people know exactly what you're talking about. Anybody who's lived around here and lots of people who live in the nation remember the mass murder," says Billie Rae Busby, a friend of Bowerman.

Families and friends of the victims had always hoped the house would be torn down a replaced with a memorial or peace garden. "That's what I was thinking, in a perfect world, that we could have done that so this horror would be a little less," says Susan Webb, Bowerman's mother.

The sale of the home puts an end to that dream.

Details about the sale are court protected but CTV News has learned a public trustee is involved and they are appointed in cases to protect vulnerable Albertans. The only survivor of the horrific crime was Lall's youngest daughter who was one-year-old at the time of the murders.

On MLS, it's clear the realtor will tell potential buyers about the home's history but in Alberta realtors are not legally required to disclose whether there were deaths, murders, or suicides in a house.

Disclosure rules fall under the Canadian Real Estate Association's code of ethics. The code says a realtor should fully disclose any information that relates to the transaction but it also says realtors don't have to go beyond legal requirements.

"Fifty years from now it may not matter, or it may, and that's where it's so grey so we have to make sure we're communicating with our clients to make sure we know what's important to them," says Lana Wright, a Maxwell realtor.

The Dalhousie house is listed for $460,000.
