DELRAY BEACH (CBSMiami) – There is no greater pain for a parent than losing a child violently, but somehow Idey Elias forces herself to push through her suffering each year on the anniversary of her daughter’s murder.

“My daughter Randi Gorenberg didn’t die of natural causes, she was shot, killed gangster style and this was done by an evil person who has to be caught,” Elias said at a news conference Thursday morning in Delray Beach.

The public plea was held at the place where Gorenberg was shot and shoved out of her vehicle on March 23, 2007. It happened at the Governor Lawton Chiles Memorial Park just off Jog Road across the street from Morikami Gardens.

At 1:54 p.m., a witness called 911 and said she heard gunshots and witnessed a woman being pushed from the passenger side of a black 2007 Mercedes Benz SUV. The assailant took off in Gorenberg’s vehicle and later abandoned it at a nearby Home Depot.

“Any little tip will help me,” a tearful Elias said.

“I know in the seven years since this happened people’s relationships change. Please help this family get some closure,” said Palm Beach County Sheriff’s Office Det. Bill Springer.

Investigators believe someone knows who committed the vicious murder.

Randi Gorenberg, a mother of two, had shopped at the Boca Town Center Mall that afternoon. She was seen leaving the mall approximately 1:16 p.m. Investigators say they don’t know what happened in the half hour leading up to the killing, but have revealed that Gorenberg did ‘not’ have an ATM card and if the assailant was looking for cash he would have been frustrated.

Gorenberg’s Kooba purse, cell phone and white PUMA sneakers were stolen and never recovered.

“We have forensic evidence. If we find the person we should be able to link them to the case,” said Detective Springer. “It is very frustrating but someday, it may take 20 years, but someday I guarantee you someone will be arrested.”

Idey Elias says she won’t find any peace until that day happens.

“If they remember anything, if they were there, please help find this person.”

If you know anything you are urged to call Crime Stoppers (800) 458-8477.
