Summary based on the NamUs case record (MP133523) and 13 other sources
In the early morning hours of May 28, 2024, 43-year-old Donald 'DJ' Hamaker set out to go fishing at a local stripping pit in Girardville, Pennsylvania, a place commonly referred to as the 'A' hole. An avid fisherman, he was known to frequent various spots, but the 'A' hole was suitable for taking his kayak. He told his mother he would be back by lunchtime, a promise that would tragically go unfulfilled. That morning, he was accompanied by two friends, having been dropped off around 3:00 a.m. to enjoy a day of fishing. The stripping pit, while a popular local spot for swimming and angling, is technically off-limits. The day took a distressing turn when Hamaker's kayak was found capsized in the water.

The circumstances surrounding the discovery of the overturned kayak raised immediate concern. Around two in the afternoon, Hamaker's friends contacted his mother, Julie Hamaker, to inform her of the situation. When she arrived, his kayak was in the middle of the water, and one of his companions was found asleep on the shore. Disturbingly, there was a significant delay in contacting authorities; a 911 call was not made until 2:16 p.m., hours after they had initially arrived at the fishing spot at 3:30 a.m. Adding to the mystery, Hamaker's fishing poles were found still tied to the kayak, while his bait remained on the shore. This detail has been particularly troubling for his mother, who questions the timeline of events.

Despite extensive search efforts, no trace of Donald Hamaker has been found. Dive teams from across northeastern Pennsylvania searched the murky and perilous waters of the strip mining pit for days, but their efforts were unsuccessful. The exact depth of the pit is unknown, making the search incredibly challenging for first responders. The official search was eventually concluded after nearly three weeks, though the investigation by the Pennsylvania State Police remains active. For his mother, the lack of answers has left her in a state of limbo, unable to find closure. The case of Donald Hamaker's disappearance is a collection of perplexing details: the delayed emergency call, the state of his fishing equipment, and the vast, inscrutable body of water that was one of his favorite fishing spots. With no new leads, his family and community are left to wonder what happened on that May morning.
