The FBI, Burlington County (New Jersey) Prosecutor’s Office, and Philadelphia Police Department Homicide Division are seeking the public’s assistance as they continue to investigate the disappearance—11 years ago today—of Danielle Imbo (née Ottobre) and Richard Petrone, Jr.

Imbo and Petrone were last seen in the late evening hours of Saturday, February 19, 2005, leaving a bar on South Street in Philadelphia. They were riding in Petrone’s black 2001 Dodge Dakota pickup truck. An extensive investigation to date has generated some promising leads; however, neither the victims nor Petrone’s vehicle have ever been located.

The Imbo-Petrone investigation remains open and active, and there is a $50,000 reward for information about the couple’s whereabouts or for information leading to the arrest of those responsible for their disappearance. Tipsters can remain anonymous.

Anyone with information that may assist investigators is urged to call the Philadelphia Citizens Crime Commission tip line at 215-546-TIPS (215-546-8477).
