"She wouldn't do that, she wouldn't do that just for fun," Jimenez said. "She was afraid of something like this happening."
There are several similarities between Flores' death and Holloway's disappearance on May 30, 2005. Most notably, the two women seem to have met van der Sloot under similar circumstances and both were captured on video leaving with him.
The lack of charges against van der Sloot have been a painful source of frustration for Holloway's friends and family, especially after he was heard in February 2008 on a reporter's hidden camera saying investigators would never find Holloway's body.
The video prompted Aruban investigators to re-open the case, but van der Sloot was never brought back to the island.
And in February 2010, a Dutch tabloid published a supposed confession by van der Sloot in which he said Holloway got drunk and fell from a balcony.
The Justice Department in Aruba was quick to dismiss the details of van der Sloot's alleged confession, telling ABC News, "We have been aware of the existence of this interview since August of last year. We investigated the claims made. The Aruban police investigated, with help from specialists with the Dutch police.
Spokeswoman for the Aruban Justice Department, Ann Angela continued to say that their "conclusion was that the statements made by Joran van der Sloot are entirely unbelievable."
But former FBI agent Brad Garrett said Flores's death may force authorities there to take another look at van der Sloot.
"It might bolster the case in Aruba, particularly if they are similar," he said.
For now, Jimenez said she wants people to know that Flores was a good person despite a troubled life.
"I want everybody to see the real Stephany, the sweet Stephany -- the good friend, good daughter," she said. "She was a good person and that's what matters."
