A 10-year-old was struggling to stay above water when a stranger at beach became her hero

Teacher’s Final Lesson: Saving a Stranger’s Life at Myrtle Beach

Goldlaner.com – The Atlantic Ocean off Myrtle Beach, South Carolina, can turn from gentle to lethal in the span of a single breath. Rip currents — narrow channels of water flowing perpendicular to the shoreline — routinely drag swimmers dozens of yards from safety before most beachgoers realize what is happening. On a late-summer afternoon in 2025, that invisible danger claimed a child’s grip on survival, and one man’s willingness to fight the current cost him his own life.

Derrick Moore, a 47-year-old elementary school teacher from outside Atlanta, Georgia, was spending his final beach day before the new school year when a scream cut through the sound of waves. More than 30 yards offshore, a 10-year-old girl named Summer McCallum was being dragged seaward by a rip current. Without a moment’s deliberation, Moore waded into the surf and began swimming toward the struggling child.

The Girl Behind the Rescue

Summer’s trip to Myrtle Beach had been arranged by her uncle, Ernest McCallum, as a way to mark the sixth anniversary of her father’s death. The family had planned a quiet day of remembrance, and Summer had been allowed a few extra minutes in the shallows as the sun dipped toward the horizon. McCallum, watching from the shore, turned his gaze back to the water and saw his niece’s head submerging and resurfacing in quick, panicked cycles.

He sprinted into the ocean immediately. Moore was already in the water behind him. McCallum pushed himself toward his niece with every muscle he had, but the current seized him, pulled him under, and swept him away. When he broke the surface again, gasping, he saw the stranger already beside Summer. He swam back to shore and returned with several other men carrying boogie boards to complete the rescue. By the time they reached the girl, Moore was gone, swallowed by the current.

Summer later told her uncle that the man had instructed her to grip his arm tightly. As the other rescuers closed the distance, he shoved her toward them so they could haul her to safety. He did not come back.

A Mother’s Prayer in St. Louis

Hundreds of miles away, Suzette Moore was traveling in St. Louis when her son’s fiancée called with news that shattered the afternoon. Derrick had gone missing while trying to save a little girl in the ocean. Suzette threw her hands skyward and prayed she would see her son again.

Those who knew him said the impulse to jump into the water for a stranger was hardly surprising. Sherry Weeks, a colleague, described him as an “energetic, polite, special hero” who “did anything and everything with a smile.” His brother, Kameron Glasper, recalled how Moore had started a soccer team at Jolly Elementary School near Atlanta — a school where he had never played or coached the sport himself — simply so the students would have an extracurricular activity of their own. Suzette Moore remembered taking her young son to the police department to be fingerprinted because she feared someone might snatch him away. He was that friendly, she said. A “free spirit” who loved people unconditionally.

The Teacher Behind the Hero

Moore spent most of his career teaching children roughly the same age as Summer McCallum. At Rockbridge Elementary School outside Atlanta, students affectionately called him “Coach.” He had previously served at Jolly Elementary, where he was named the 2024 teacher of the year. His colleagues and families described a man whose generosity extended far beyond the classroom — a man who built teams, coached informally, and treated every child as though they mattered personally.

The rip current that killed him is a well-documented hazard along the South Carolina coast. The National Weather Service and local lifeguard agencies regularly warn that rip currents account for the majority of ocean rescues along the Atlantic seaboard, and that swimming parallel to shore is the recommended escape technique. For a child caught in a panic response, however, the current’s grip is nearly impossible to resist without outside intervention. Moore provided that intervention at the cost of his own life.

Aftermath and Tribute

According to the Myrtle Beach Police Department, Moore’s body washed ashore on August 8, one day after the girl’s rescue. McCallum said Moore had saved not only Summer’s life but his own as well — that without the stranger’s intervention, the current would have claimed both uncle and niece.

“He was a hero before that day. He was a hero to his family, his kids, his daddy, his mama, his family. He was a hero then. He just became a hero to everybody else on Friday,” McCallum said.

Summer, holding her uncle’s hand, told reporters that she did not yet fully grasp the gravity of what had happened, though she knew loss intimately, having endured several family deaths in recent years. She offered a message she wished she could deliver directly to Moore:

“Thank you, I really owe my life to you. I get to go back to school and love my family more than I did.”

McCallum said he wanted to reach Derrick Moore’s family to express gratitude for the selfless act and to learn more about the man behind the rescue. Moore left behind four children, a fiancée, a mother, and a community of former students who remembered him not as a stranger who died in the surf, but as the coach who started a soccer team no one else would have bothered to organize.
