The family of Roseline Conteh filed a wrongful-death lawsuit last week against the owner of the building that collapsed at 22nd and Market on June 5, the Salvation Army and 17 others.
Conteh, 52, an immigrant from Sierra Leone, died in the collapse when an under-demolition building collapsed on top of the Salvation Artmy Thrift store while she shopped.
In total, six people died and 14 were injured.
One of the woman's children filed the suit on Thursday. The suit claims the property owner, Richard Basciano, failed to comply with necessary safety requirements. It also claims the thrift store ignored numerous warning signs and was negligent in its decision to remain open during the construction.
The family is represented by Steven G. Wigrizer and Jason S. Weiss. The firm filed a similar suit last week on behalf of Mary Lea Simpson, 24, who also died while shopping in the thrift store.
More than a dozen lawsuits have been filed since the collapse.
