After this column posted on Philly.com on Friday, Lauren Hitt, a spokeswoman for Mayor Kenney, said the city would shut the building and dispatch social workers to help those inside. Later Friday, the city’s Department of Licenses & Inspections checked the building. On Saturday, the owner had a crew seal the former church’s doors. On both days, city social workers went to the site to offer help to those inside, but no one accepted their offer.
