PHILADELPHIA -

Relatives of a mother of eight killed in a deadly building demolition while shopping for clothes in a Philadelphia thrift store are bringing the second wrongful death suit in the collapse that claimed six lives.

Roseline Conteh, 52, an immigrant from Sierra Leone who worked as a nursing assistant, was among the victims when a four-story building tumbled onto the Salvation Army store in June.

The suit alleges negligence, carelessness and "conscience-shocking behavior" on the part of the defendants.

Messages left for the Salvation Army and the owners of the building and demolition firm didn't immediately return messages seeking comment. An attorney for the equipment operator declined comment.

Last week, a wrongful death suit was filed by the family of an arts school graduate killed.
