Nassau County police are actively searching for a suspect accused of repeatedly vandalizing a residential lawn in North Massapequa, New York. The incident involves a man who allegedly targeted the property of John Giurco on North Linden Street on three separate occasions: July 24, July 26, and September 19 of 2026. During these early morning hours, the suspect is reported to have dumped an unknown substance onto the lawn, causing an estimated $5,000 in damage. Police describe the individual as a male approximately 60 years old, standing 5 feet 8 inches tall with gray hair. The suspect was captured on video wearing shorts and a hooded sweatshirt while walking across the property. Mr. Giurco stated that he recognizes the individual from previous encounters, including an incident in May where the man, who was walking two dogs, threatened Giurco's life while he was gardening. Giurco expressed concern that the vandalism could escalate into more serious violence, noting his fear that the suspect might attempt something worse. Neighbor Laura Millard also reported seeing someone taking pictures of the property several months prior. Despite the significant damage, Giurco has stated he does not plan to repair the lawn, believing the harassment will continue. Authorities are urging anyone with information regarding the identity or location of this suspect to contact the Nassau County Police Department. The investigation remains ongoing as police seek to apprehend the individual responsible for the criminal mischief.
