Summary based on the NamUs case record (MP20818) and 8 other sources
On a day that began like any other, 46-year-old Robert Mayer left his home in Dix Hills, New York, on the morning of June 14, 2013, for his job as an electrician in Brooklyn. A married father of two, he was looking forward to a Father's Day barbecue that weekend and had spoken to his wife, Ida, around 9:00 a.m. to discuss plans, including picking up lobsters and oysters. That morning, there was nothing to suggest the devastating turn his family's life was about to take. Robert, a man described as a devoted husband and father, would vanish, leaving behind a perplexing mystery that continues to haunt his loved ones. He was last seen wearing a gray polo shirt with 'J.C. Electrical' inscribed on it, light-colored blue jeans, and either black work boots or white sneakers. He also had on Ray-Ban sunglasses and a gold wedding ring on his left hand.

The timeline of Robert's last known movements has been pieced together through various accounts and electronic data. After leaving his job in Brooklyn in the early afternoon, his cell phone pinged near the Northern State Parkway in Melville around 1:45 p.m. By 2:15 p.m., security footage captured him at Arrow Scrap Yard in West Babylon, where he sold some scrap metal for approximately $300. Shortly after, at 2:41 p.m., a neighbor's security camera recorded Robert's red 2004 Pontiac GTO returning to his home. The car was seen leaving just ten minutes later, though it is unknown who was driving. When his wife, Ida, later searched the garage, she made a bewildering discovery: Robert's cell phone, wallet, ID, and the $300 cash from the scrapyard were all there. Adding to the puzzle, his green mountain bike and a shotgun were also noted to be missing from the residence.

The day after he was last seen, friends of the family found Robert's cherished Pontiac GTO abandoned and locked in the parking lot of the Deer Park Long Island Rail Road station. This was highly unusual, as his family said he never took the train and was meticulous about the car's security. Upon inspection, it was discovered that the driver's seat had been adjusted for someone much shorter than Robert, and his usual work tools and lunchbox were missing from the trunk. In the years since his disappearance, there has been no activity on his bank accounts or social media. The investigation into Robert Mayer's case remains open, but with few clues and no definitive answers, his family is left in a state of agonizing uncertainty. The case is a collection of strange and disconnected facts: a loving family man planning for a holiday, a mysterious return home, personal belongings left behind, and a car abandoned in an unlikely place, all culminating in a silence that has now lasted for over a decade.
