Police are investigating a possible murder-suicide in New Windsor Friday.

Neighbors say 38-year-old Griselda Espinal, an NYPD detective, was arguing with her estranged husband, Francisco, before the shooting. Police say Francisco killed his wife with her police-issued pistol before he went outside the home and shot himself in front of the couple?s three children. They report that there was an loud argument in the house before the incident.

Neighbors also say the couple?s three kids, all under the age of 13, pleaded with their father not to kill himself.
