NEW JERSEY — The New Jersey State Police is remembering Sgt. First Class Sean William Acker, a longtime trooper who died Wednesday after complications connected to a duty-related injury, officials announced.
Acker, who had grown up in Howell and was assigned to the Division Staff Section, had served the New Jersey State Police for more than 19 years. Acting Superintendent Lt. Col. David Sierotowicz said Acker’s death followed years of serious medical issues that originated from injuries sustained during his career.
A member of the 145th State Police Class, Acker joined the agency in 2006 after previously serving in the United States Air Force. He enlisted in 1998, rose to the rank of staff sergeant and was among the original members of the Air Force’s elite “Ravens” unit, according to the Tunnel to Towers Foundation.
Within the State Police, Acker was widely known for his leadership at the Academy, where he served as head instructor of the Physical Training Unit. Fellow troopers said he demanded discipline and resilience, frequently running miles each day alongside recruits to push them beyond their perceived limits.
Years of intense physical training eventually caused significant damage to his hips, leading to a double hip replacement. While preparing to return to active duty, Acker suffered further complications. According to the Tunnel to Towers Foundation, a blood clot led to a pulmonary embolism and cardiac arrest, resulting in a traumatic brain injury and a prolonged recovery marked by additional medical setbacks.
Acker later became a recipient of the Tunnel to Towers Smart Home Program, which provided specialized housing support as he continued rehabilitation.
He is survived by his wife, retired State Police Capt. Lisa Acker, and their children, Connor and Samantha.
