Orsolya Gaal was pronounced dead at the scene after someone called 911 to report a suspicious bag with blood on it.
NYPD detectives traced the blood stains several blocks away to a home in Forest Hills, a residential neighborhood in Queens.
Gaal went out with friends on Friday night and was seen back at her home before surveillance video captured an "unknown individual" dragging the wheeled duffel bag in the early hours of Saturday morning, according to the New York Post.
Her body was discovered about four hours later.
Gaal's husband and eldest son were away at the time of her death, but PIX11 reports that the family received a chilling message for her husband that said, "Your whole family is next."
The couple's younger 13-year-old son was found on the top floor of their home after police traced the bloodstains back to the neighborhood, according to The Post. The NYPD doesn't believe he left the home overnight.
The New York City Medical Examiner's Office will perform an autopsy and determine Gaal's cause of death.
