Enhanced sketch of Boca mall murder 'persons of interest'

BOCA RATON, FL -- It has been 20 months since Randi Gorenberg walked out of the Town Center Mall toward her SUV, only to be discovered murdered an hour later, and 11 months since Nancy Bochicchio and her 7-year-old daughter Joey were discovered shot to death in their SUV at the same mall.

Since then, there has been stepped up mall surveillance, a composite sketch of the suspect, a third possible victim who survived and grainy footage of two men trying to make $1,000 in purchases in Massachusetts and Connecticut using Randi Gorenberg's credit card.

The sketch is now enhanced.

John Walsh of "America's Most Wanted" is back in the area and displaying a picture of two young men who could be tied to the case.

Sheriff Ric Bradshaw doesn't necessarily believe they are suspects but wants to talk to them just the same.

“My sense is they just got the card and used it, that doesn’t mean they don't know the person they got it from," said Sheriff Bradshaw.

On South Beach Wednesday was a familiar crime fighter taping a segment for "America’s Most Wanted.”

With him was Sheriff Bradshaw, who has a team of detectives trying to help Boca Police break a case the Sheriff acknowledges has gotten under his skin.

"There's hardly a day goes by I don't think about it,” Bradshaw says.

Each man is saying that when they think about the case, little Joey stares back at them, neither necessarily believing the two men in the sketch are killers.

So where is the case?

It’s stalled.

The first anniversary of the murder of a little girl and her mother at a high end Mall, in a high priced town approaches.

"Somebody murdered two women and a seven-year-old girl,” Walsh says, “They have to be taken off the street. I'm the father of a murdered child."

Though 40 percent of the crimes addressed on "American Most Wanted" are solved, it is just a TV show, not an investigating agency.

The fact that this is the fourth time the show has covered the mall murders says a lot about the lack of progress of the investigation.
