CLEVELAND -- Cleveland police, the FBI and the coroner are busy collecting evidence that everyone hopes will lead to 11-year-old Shakira Johnson's killer. Her body was found last week in a field on East 71st Street and Aetna after she was reported missing last month.

If and when a suspect is charged, the case will fall in the hands of Cuyahoga County Prosecutor Bill Mason.

According to NewsChannel5's Paul Kiska, Mason is confident that the killer will be caught and caught soon.

"I'm very confident about the information we have available, that we're gonna get the break we need to bring somebody in. We're gonna get him," Mason said. "I'm certain with the effort we've got going forward, we're gonna get our person.

"We're hoping they're going to be able to find something that's going to match a defendant or offender. We're hoping that's gonna happen soon."

For police and prosecutors, the best tool, next to forensic evidence, is a witness, Kiska said. Without a witness, cases almost always go back to forensics.

"What we really look for is a statement that leads us to the person or a witness about a person. But forensics are great -- a fingerprint, DNA are great matches nobody has except to the person we're accusing," Mason said.

Police have questioned registered sex offenders living near Johnson. The focus on sex offenders is because they have a high rate of repeating their crimes.

"Sexual offenders generally have a high recidivism rate. They get rearrested for sexual crimes at a later date," Mason said.

City Councilman Zack Reed represents Ward 3, which includes Johnson's neighborhood. He also heads up the council's public safety committee. Reed scheduled a special meeting next week to search for ways to keep better track of registered sex offenders.

"They weren't where they were supposed to be. We want to know where those offenders are," Reed said.

So far, no suspect has been named.
