On Wednesday, the FBI said in a statement, "Our office remains unwavering in seeking justice for Danielle and Richard, their loved ones, and our city." The bureau added it's offering a $15,000 reward for info leading to an arrest and conviction in Petrone's and Imbo's disappearance.
Meanwhile, Imbo's brother, John Ottobre, declined to talk on camera but thanked investigators in a message and wrote: "It's been an incredibly difficult 20 years without answers about Danielle's disappearance. The pain of not knowing what happened to her has never lessened, and our family continues to hope for the truth."
In the past 20 years, this family never had a funeral for Richard Petrone. His absence has left a hole now filled with desperation for the truth.
"Just let us know something. Let us know something, please let us know what happened," Marge Petrone said. "After all this time, unburden yourself with this guilt and let us know what happened to my son and Danielle."
Twenty years ago, Richard Petrone and Danielle Imbo went missing on South Street in Philadelphia. What happened remains a mystery.
