A former battalion chief for the Deptford Fire Department has died this weekend following a response to a fire. Former Battalion Chief Jeff Pfeiffer suffered a cardiac arrest at the Almonesson Lake Firehouse on Thursday night, according to the Gloucester County Office of Emergency Management. Pfeiffer served the township as a firefighter for over 50 years. The Deptford Fire Department first announced his passing on Saturday. "It is with sincere grief that we share that we have lost former Battalion Chief Jeff Pfeiffer," the department said. "We will share more details on this wonderful and heroic leader and firefighter in the days ahead." As the medical emergency happened following a report of smoke at a residence, Pfeiffer's passing has been recognized as a Line of Duty Death.
