An inspector who had some involvement with the building that collapsed last week in Philadelphia has committed suicide. Take a look at images of the building collapse that killed at least six people and injured more than a dozen.
Ari Barker, who witnessed the aftermath of the collapse, told CNN the building collapsed on top of a thrift store next door, as well as a busy sidewalk.
The Occupational Safety and Health Administration has been told it was an accident at a demolition site, and has investigators on the way.
Bystanders and construction workers rushed in to search for people trapped under the rubble. Rescue crews soon arrived and asked the public and news helicopters to back off to allow searchers to listen for people trapped under the debris.
University of Pennsylvania Hospital was treating four patients from the collapse, according to hospital spokesman Stephen Graff. Hahnemann University Hospital is treating two patients, according to hospital spokeswoman Gianna DeMedio. They are were fair condition.
Twelve people rescued earlier were taken to area hospitals with minor injuries. Shortly before midnight, authorities pulled out 61-year-old Myra Plekam alive. She was the 14th survivor.
The fire department was called to the site at 10:43 a.m., Capt. Jeffrey Thompson told CNN. Thompson said it wasn't immediately clear whether it was an apartment building or an adjacent building scheduled for demolition.
Video from WPVI showed two people helping a third person, apparently hurt, away from the rubble. It also showed emergency personnel walking on and around rubble on an exposed area of a ground floor.
"I was in my office in the high rise across the street and felt and heard a rumbling, a very unusual sound," eyewitness Ari Barker told CNN.
Two people remained trapped under "tons of rubble," early Wednesday afternoon, Fire Commissioner Lloyd Ayers told reporters. "We have located them and we're going to continue until we can get them out and we can get them to hospitals."
Here is what the building looked like before Wednesday's collapse.
"This happened a block from my workplace," CNN iReporter Adrienne Madenspacher said. "We had no idea what the sirens were about until one of the employees passed by. It's an old four-story apartment building connected to a Salvation Army amidst the high rises. Streets are closed off from cars and pedestrians."
CNN iReporter Matan Segal said of the building collapse, "I was extremely concerned because a close friend of mine lives right by the intersection of 22nd and Market. I read the news report ... and saw the graphic imagery, and felt the urge to head to the scene immediately. On my way over all I could hear is sirens."
CNN iReporter Josh Rozell speaks about the building collapse, saying "I saw streets closed from 21st Street to 30th Street, and multiple rescue vehicles, including about five ambulances. Several firefighters were still digging through the rubble trying to find any victims."
More water guzzling lawns may be replaced by drought tolerant plants throughout Santa Barbara because of the on going drought, and in some cases, homeowners will be getting a cash rebate for making the change.
