More than a pound of heroin was discovered inside the body of a man stuffed into a suitcase and dropped off in a Yonkers park, police say.

The remains of the victim, an unidentified Hispanic man in his 50s or 60s, were found last Thursday by an employee of Tibbetts Brook Park.

Investigators believe one of the 40 heroin packages exploded in his stomach, and he died of an overdose. So far, however, no autopsy has been conducted to confirm that theory.

According to authorities, the man was probably a drug mule who was transporting heroin from the Dominican Republic to the New York area. Police are not sure, however, whether the man?s final destination was Yonkers or another town in Westchester County.

The Westchester medical examiner is not expected to determine a definite cause of death until sometime next month. For now, police will be investigating the man?s death as a homicide.

In an attempt to identify the victim, Yonkers police ran his fingerprints through the national database, but so far no match was found. They believe he does not have a criminal record in the U.S. because he was most likely a citizen of the Dominican Republic.

Anyone with information about the man?s death is asked to call a tip line at 1-800-898-TIPS.
