Seidel's bail was set at $500,000 cash, Webb-McRae said.
The accident occurred in Millville about 2 a.m. Sunday.
Webb-McRae said Seidel allegedly was trying to flee from Millville officers who were pursuing him for several motor vehicle violations, including hitting another police cruiser. The two officers involved in the crash apparently were not part of that pursuit.
Killed in the accident was Christopher Reeves, a 1991 Millville Senior High School graduate who served in the Marine Corps before joining the Millville force eight years ago. He also had served with the city's Fire Department.
Reeves, who had recently been moved to the overnight shift, was pronounced dead at the scene. His survivors include his wife, Susan, a fellow Millville police officer, and their 2-year-old son, Alexander.
The other officer in the cruiser, Johnathan Seidel, suffered arm injuries and remained hospitalized Monday night. He was scheduled to undergo surgery, and Webb-McRae said he is not related to the accused motorist.
Johnathan Seidel, 27, had joined the Millville force last month after serving with the Salem County Sheriff's Department for several years. He was riding with Reeves as part of a field training program.
