It's been one month since a building collapse in Center City killed 6 people and injured 13 others.
Kadie Conteh's sister Roseline was shopping inside the Salvation Army thrift store at 22nd and Market, when a building undergoing demolition came crashing down onto the store.
"Everyday I cannot even believe it. I cannot believe that I lost my sister," said Conteh, who tells NBC10's Matt DeLucia she has a lot of sleepless nights, thinking about what went wrong.
"It bothers me a lot because how can somebody go and have a short building and then somebody go demolish a tall building under a short one? I don't know," said Conteh.
A lawyer representing six of the injured victims and the estates of two who died in the collapse tells NBC10's DeLucia he sent his own investigators to the collapse site.
"Our experts have a very good idea at this point of what happened, by looking at the scene and looking at the debris from the scene," said Attorney Larry Bendesky.
Bendesky says he will soon file lawsuits in the case.
"In the future, demolition sites can be planned and handled so that the job is done more safely, so something like this never happens again," said Bendesky.
