A recent high school graduate from Tioga County was discovered dead in the Susquehanna River on May 11, 2026, bringing a devastating conclusion to a massive two-state search that mobilized emergency crews and community volunteers across New York and Pennsylvania.
Dalton G. Malmstrom, 18, who graduated from Owego Free Academy in 2025, was recovered from the river by the State Police Underwater Recovery Team alongside K9 unit members, according to New York State Police. He had been missing since the morning of May 9, when he walked away from his Nichols home following a dispute with relatives.
Authorities have not disclosed how Malmstrom died.
A School Community in Mourning
The Owego Apalachin Central School District has mobilized its crisis intervention plan to support grieving students and staff following news of Malmstrom’s death. Counselors were made available throughout the week as the community processes the tragedy.
“Our hearts are with the Malmstrom family during this unimaginably difficult time,” district officials said in a statement, adding that “Dalton remains a well-known member of the OACSD community, with relatives and friends currently enrolled at Owego Free Academy.”
District administrators emphasized that providing emotional support and resources to help students “navigate the complex feelings that arise” remains their top priority.
Two Days of Searching Across Two States
The search for Malmstrom escalated rapidly into a multi-jurisdictional operation after his May 9 disappearance. Emergency crews deployed ground teams, aerial drones and K9 units along the river corridor, with volunteers from both New York and Pennsylvania remaining active through May 11 as the effort intensified.
The Susquehanna River, one of the East Coast’s longest waterways, presents significant challenges for search operations. The section flowing through Nichols features dense vegetation, steep banks and farmland that complicate both ground and water recovery efforts.
What began as a missing-person case transformed into a large-scale search drawing resources from across the region. Geography played a key role: Nichols sits in New York’s Southern Tier, roughly midway between Binghamton and Elmira, just north of the Pennsylvania border.
The teenager’s body was located in the river on the afternoon of May 11. Police have not revealed the specific recovery location or established a timeline of Malmstrom’s movements after he left home.
The May 9 Morning Disappearance
Malmstrom departed his residence in the 2100 block of East River Road at approximately 7:45 a.m. on May 9 after arguing with family members, investigators said. His relatives reported him missing that same day, telling troopers he was “not acting like himself” before leaving.
Described as 5-foot-10 with dark hair, the teen was last observed wearing a dark-colored shirt. East River Road sits near the Susquehanna River in an area of Tioga County close to the Pennsylvania state line.
Questions Remain as Investigation Continues
Investigators have not classified the death as suspicious but have not eliminated any possibilities. Police have declined to discuss what evidence, if any, was recovered along Malmstrom’s presumed route from his residence to the river, and have not commented on whether surveillance footage or witness statements helped focus the search.
The family dispute on May 9 and their concerns about his unusual behavior have emerged as important elements of the case, though authorities have not publicly connected those circumstances to any particular theory about how the teen ended up in the Susquehanna.
The investigation remains active. Anyone with information regarding Malmstrom’s activities on the morning of May 9, or details that could help reconstruct the timeline between his departure and disappearance, is urged to contact authorities. The New York State Police can be reached at 607-561-7400.
In Nichols, home to fewer than 2,500 residents, the tragedy has deeply affected the tight-knit riverside community. Many who participated in the volunteer search were neighbors, classmates and family friends — the same people who had hoped the extensive effort would bring Malmstrom home safely.
The family has not yet released funeral arrangements, but a GoFundMe campaign seeking $20,000 has been established to assist with burial costs and everyday expenses.
