CHICAGO (CBS 2) There has been a new development as city officials investigate a deadly fall from a South Side porch. A building inspector will be fired for lying about how thoroughly he checked out 5509 South Bishop last Friday. One day later, a nine-year-old girl fell through a third-floor porch railing and died.

As CBS 2's Dana Kozlov reports, this isn't the only investigation into a potentially faulty railing.

Officials are also trying to learn why another porch railing -- this one in Lincoln Park -- gave way over the weekend, seriously injuring two people. In the first case problems were documented and allegedly ignored. In the second, City officials can't say when the porch was last inspected.

25-year-old Allison Gwin just moved to Chicago from Alabama. On Saturday she went to 439 West Webster to help someone move when, suddenly, a porch railing gave way. Relatives say Gwin is now in intensive care with a fractured neck, back, ribs, pelvis, and, possibly, a punctured lung. A friend who also fell underwent surgery.

Chicago Building Inspector Stan Kaderbek said, ?The City has no record of 311 complaints concerning the condition of the Webster porches."

Those victims lived, but 9-year-old Tiara Woods did not. She died Saturday after a railing at 5509 South Bishop gave way.

Tenant Rosie Downs says she'd repeatedly complained to managers about problems in the building and stopped paying rent. Her lawyer even prepared a document last week and filed it today highlighting railing concerns. But owner Alec Brikva says he wasn't aware of them. "Never received any complaints regarding the porches -- they're brand new; they're two years old," he said.

"The building does have a troubled history," Kaderbek said.

And Commissioner Kaderbek says that's one reason an inspector was sent to 5509 Bishop last Friday: to inspect an interior stairwell after a tenant fell through it and broke her ankle. That inspector, Charles Walker, later claimed he inspected the entire building including the porch railing. But Kaderbek says Walker lied. "I can only assume that Walker panicked on Monday after hearing that a young girl had fallen off the porch and died as a result," he said.

Kaderbek has now moved to fire Walker and that is part of the ongoing investigation.
