PHILADELPHIA (WPVI) -- Philadelphia's top cop says changes have been made to the city's 911 system and more are on the way.
Interim Commissioner John Stanford outlined those changes during a hearing before City Council on Tuesday.
It was held in response to a mishandled 911 call which led police to the wrong location after a shooting was reported on July 2.
It was later revealed that Kimbrady Carriker allegedly shot Joseph Wamah Jr. through the front door of a home in the 1600 block of South 56th Street.
However, police officials later revealed that officers were dispatched to the 1600 block of North 56th Street. They didn't find anything and left.
Carriker is accused of then carrying out a mass shooting in the city's Kingsessing section the next day, killing four more people.
During Tuesday's hearing, Stanford said 911 dispatchers are now directed to ask additional questions about the exact location of a caller's emergency.
That includes whether the street has a directional indicator.
Stanford also said managers will make sure callbacks are made and recorded.
He said the department is also integrating a new product that will help dispatchers get the information they need.
