The husband, a retired NYPD crime scene sergeant, was pronounced dead at the scene. A UPS delivery man working in the area reportedly saw the body and called police.
Authorities say the wife was immediately placed in handcuffs and led out of her house by detectives. Crime scene tape was strewn across the front yard and sidewalk.
One neighbor started to clap as she was paraded by before a woman made him stop.
It appears the wife used her husband's service revolver.
