An interlocking ring. Missing shoes and CD case. And a mysterious white Chrysler sedan.
Together, these bits of seemingly random evidence from an unsolved Palm Beach County murder from last March could potentially lead investigators to the man who bound, robbed and killed a mother and her daughter in December.
America's Most Wanted host John Walsh, who has profiled the cases extensively on his show, believes the same person killed Randi Gorenberg in March and shot Nancy Bochicchio and her daughter, Joey, in December.
Police are not ready to say that definitively, but detectives acknowledge the similarities are too great to ignore. "It's a fascinating mystery," said Paul Miller, a spokesman for the Palm Beach County Sheriff's Office.
Last week, a task force made up of detectives from the Sheriff's Office and Boca Raton police made public new details of Gorenberg's death March 23.
Like the Bochicchios, Gorenberg was abducted during the day after leaving the Town Center at Boca Raton. In both cases, the victims were carjacked in their dark-colored sport utility vehicles.
The killer shot Gorenberg, who was alone, and left her body on the side of the road not far from the mall.
Gorenberg had just bought a John Legend CD, which authorities found inside her Mercedes SUV stereo - the vehicle that the killer dumped behind a nearby Home Depot.
The CD's case, Gorenberg's sneakers and her purse were missing when the SUV was found less than an hour later.
She was wearing a piece of costume jewelry that has friends and relatives scratching their heads. An interlocking ring was found on her finger that people close to her had not seen before - raising the eerie possibility that the killer may have slipped it on her before shooting her, Miller said.
Police are also intrigued by a white Chrysler 300 spotted on surveillance video following what appears to be Gorenberg's SUV behind the Home Depot. It is possible the driver of that vehicle helped the killer escape.
Nine months later, the Bochicchios were murdered.
Last Thursday, authorities released a new composite sketch of the man they believe killed the mother and daughter and left them in the Boca Raton Town Center Mall parking lot last year.
The victims were found dead in their black 2007 Chrysler Aspen, which was still running, in the parking lot.
Police believe the Bochicchios were abducted after 3 p.m., shortly after they exited the mall near Sears and Neiman Marcus.
The assailant - who bound them with duct tape, plastic ties, handcuffs and goggles - forced them to drive to an ATM and take $500 from their account.
A 911 call was placed by Bochicchio's cell phone, but was disconnected before she could talk to dispatchers.
The killer is described as close to 6 feet tall, with a medium build and between 18 and 25 years old. It is believed that he has a ponytail. A reward of up to $350,000 has been offered for his arrest.
