The collapse took place at about 10:30 a.m. Wednesday in a pair of low-rise buildings at 22nd and Market Streets, one of which was under demolition at the time (See Related Story).
Authorities said when the building under construction collapsed, it sent debris through the wall and roof of the adjacent one-story Thrift Store that was fully operational at the time, nearly flattening it.
Eyewitnesses recalled hearing a loud rumbling sound before the collapse.
During a news conference Thursday morning, Mayor Michael Nutter said approximately 75-percent of the collapse site had been searched and 42 emergency personnel had remained on the scene. The remaining 25-percent was completed by 3 p.m. Thursday.
“Today, we mourn the loss of six Philadelphians who perished in the terrible tragedy at 22nd and Market streets on Wednesday. Our deepest condolences go out to the families and friends of the deceased,” said Mayor Michael A. Nutter. “I ask all Philadelphians to remember those who perished and their families in their prayers and thoughts.”
Nutter identified the deceased as: Kimberly Finnegan, Borbor Davis, Juanita Harmin, Mary Simpson, Anne Bryan and Roseline Conteh (Read: About The Victims).
The following individuals were among those injured in the collapse: Susan Randall, Betty Brown, Shirley Ball, Linda Bell, Jennifer Reynolds, Nadine White, Margarita Agosta, Richard Stasiorowski, Rosemary Kreutzberg, Rodney Geddis, Felicia Hill, Daniel Johnson and Myra Plekan.
Mayor Nutter praised the rapid response and prolonged effort of the city’s first responders as well as those citizens who selflessly entered the demolition site in the minutes after the collapse to help in the search for survivors. “Reports yesterday identified a number of individuals who took quick action, including Jordan McLauglin, Ray Kauffman, Bill Roam, Patrick Glynn and Brian Mullins. On behalf of the City, I want to thank them for their quick thinking and courage,” Mayor Nutter said.
