Investigators believe the women found dead, bound together in the Hudson River may have been lovers who jumped to their death in a suicide pact.

As CrimeOnline previously reported, the bodies of two young women were found on Wednesday afternoon near Riverside Park on Manhattan’s Upper West Side. Authorities reportedly said the women’s ankles were bound together with what appeared to be duct tape, and that the bodies also appeared to be bound at the waist. Both women are believed to be between 25 and 30 years of age and were wearing coats. Their bodies did not show any visible signs of trauma, but a medical examiner is working to determine the cause of death.

The New York Post reports that an investigation is probing the possibility that the women were romantically involved and jumped from the George Washington Bridge in a suicide pact. The report did not indicate what is leading investigators to believe the deaths were intentional.

Police are seeking leads to help identify the two women, and have released a sketch showing that the women share a physical resemblance. According to the New York Post, NYPD Crime Stoppers is offering a $2,500 reward for information that helps lead to a positive identification of the deceased women.
