New Jersey State – The New Jersey State Police and the wider law enforcement community are mourning the death of Sgt. First Class Sean Acker, a veteran trooper who died on February 4 after suffering a medical condition stemming from a work-related injury, according to officials.
In a statement shared on social media, Acting Superintendent Lt. Col. David Sierotowicz announced Acker’s passing, calling it an “untimely loss” and extending the department’s support to his family. Acker, badge number 6889, served for more than 19 years with the New Jersey State Police and was a member of the 145th State Police Class, holding an assignment within the Division Staff Section.
Born in Abington, Pennsylvania, Acker grew up in Howell Township, New Jersey, alongside three brothers. Before beginning his state police career in 2006, he served in the United States Air Force, a chapter of his life that friends say shaped his sense of discipline and service.
“His legacy is reflected not only in his professional accomplishments, but in the countless lives he touched through his kindness, generosity, and sincere care for others,” his obituary reads. Colleagues echoed that sentiment, noting that Acker was known as both a steady leader and a compassionate mentor.
Acker is survived by his wife, Retired Captain Lisa Acker, and their two children. The New Jersey State Police described the Ackers as a family deeply rooted in public service, a reality that has intensified the emotional response within the ranks.
Experts note that deaths linked to work-related injuries, even years later, underscore the long-term risks law enforcement officers face. “These cases remind the public that the dangers of policing don’t always end when a shift does,” said a retired law enforcement health advocate familiar with officer injury trends.
As tributes continue, the department says it remains committed to honoring Acker’s service and supporting his family, reflecting a legacy defined by duty, sacrifice, and humanity.
