GARNERVILLE - A White Plains postal worker has been charged with murdering his girlfriend.

Police say they got a call from witnesses about an argument on the balcony of an apartment at 28 Forrest Drive in Garnerville Wednesday shortly after 10 p.m. Haverstraw police told News 12 that when they got there, 37-year-old Nixon Bourguignon, who is a fill-in mail carrier at the White Plains Post Office, was on the outside deck. They say he quickly went inside and turned off the lights.

Once they entered the apartment, police say they found Shannon Coleman, 29, dead of asphyxiation in the bedroom. They then found Bourguignon hiding in the closet with wounds to his arms and throat. They say Bourguignon told them he had cut his throat with a knife.

Bourguignon told police after his arrest that Coleman had yelled at him for watching too much SportsCenter. He says he got angry because she was texting a man who is the father of her 10-year-old son. Bourguignon says he was afraid they might be getting back together.

Coleman and Bourguignon had a 7-year-old boy together, who was also living with them. Officials say Coleman's two sons, who were home at the time, were not hurt in the incident.

Coleman worked for many years at Bardonia Pediatrics. The staff was too distraught to talk, but her brother Jordan Higdon told News 12 that his sister was a great person and mother. He says she was trying to leave Bourguignon when she was murdered.

Bourguignon has been charged with second-degree murder. He was arraigned at Haverstraw Town Court this morning and remanded to the Rockland County Jail without bail.
