Alan Justad, 71, died in the crane collapse. Now his family is suing

Attorney David Beninger represents the family of Alan Justad, one of four people killed on Saturday when a tower crane fell from a building onto Mercer Street in downtown Seattle.

"His loss won't be in vain,” Beninger said, “and others won't have to worry as they're driving downtown that the rules aren’t being followed and enforced."

Beninger says the firm is at the beginning of the investigation phase and didn’t specify which companies would be included in a lawsuit.

Five companies involved with the crash are being investigated by the state.

Benninger points to the dozens of cranes in Seattle and says the pace of the growth in the city can't take priority over public safety.

"We shouldn't have to worry that that trust is being betrayed by people that are cutting corners and not doing things right,” he said.

He said the Justad family would file a suit in coming weeks.
