Missing Mom, Abandoned Baby -- Boyfriend on the Run?

Interpol has joined the search for New Jersey woman last seen in early June.

July 5, 2007 — -- The baby was found in a parking lot. The mother is missing. The boyfriend is on the lam in Italy. Now Interpol, the international police organization, has joined the search for Amy Giordano, 27, a New Jersey mother who was last seen June 9 in a ShopRite with her boyfriend, Rosario DiGirolamo, 32, and their 11-month old son, Michael.

Two days later, Michael was found alone in a Delaware hospital parking lot, and the mystery of what happened to his parents continues to baffle.

Police hope that Interpol, which is currently reviewing the details of the case, will help locate the missing father. Delaware State Police hope to find surveillance footage from the Milan Airport to see whether DiGirolamo was traveling alone or if he met anyone when he landed.

Boyfriend Under Suspicion

DiGirolamo has been classified as a "person of interest" in the case by both Delaware and New Jersey authorities. On June 28, the Delaware State Police acquired an active arrest warrant, charging DiGirolamo with reckless endangering in the first degree and child abandonment.

Signals from DiGirolamo's cell phone pinged off a tower adjacent to the hospital where the baby was found, said police. These calls were transmitted June 9, the same day the baby was abandoned.

And while police would not divulge precise details of the phone calls and their content, they believe the phone records narrow the time frame in which the child was abandoned to a 10-minute window.

Police said DiGirolamo went back to work in New Jersey the day after his son was found in the hospital parking lot before leaving the country five days later.

"We understand that he then went back to New Jersey, within days after he abruptly left work -- left his computer on, his office as it was, didn't close anything -- just took off," said says Delaware State Police Cpl. Jeffrey Whitmarsh.

DiGirolamo was last seen June 11 at his job at Conair Inc. The Times of Trenton reported that after a number of weeks absent from work at the health and beauty manufacturer, DiGirolamo was fired.

Authorities have a record of DiGirolamo calling his father in Brooklyn June 12, and June 14 he bought a ticket on a Continental Airlines flight from Newark, N.J., to Milan, Italy, according to Casey DiBlasio, spokeswoman for the Mercer County Prosecutor's office.

On that very same day, the abandoned baby was identified as Gordiano and DiGirolamo's son, after their landlord, Mike Vanderbeck, spotted the baby on the news.

U.S. Investigation Continues

In addition to contacting Interpol for help with the overseas investigation, authorities in New Jersey and Delaware have conducted several searches of Gordiano's apartment, DiGirolamo's office and his Lexus, which the prosecutor's office said was found June 26 in a residential area in Staten Island, N.Y..

"Trace amounts of blood were found in various locations in [Gordiano's] apartment and further forensic testing is being performed now," according to prosecutors.

A purse was also found in a closet in the back of the apartment, and authorities don't believe Gordiano had a passport or a driver's license.

A friend of Gordiano's told Delaware authorities that Gordiano had mentioned a fight she'd had with DiGirolamo just before she disappeared. While no threats were confirmed, she said Gordiano had discussed leaving DiGirolamo.

Vanderbeck, Gordiano's landlord, said she was a "good tenant." He told ABC News that DiGirolamo, who paid the $850 rent, came by "a couple of times a week" because Gordiano didn't have a driver's license.
