A Baldwin man was arraigned on manslaughter and other charges in the fatal Labor Day weekend shooting of a Pennsylvania man during an argument outside the suspect's home, police said.

Homicide squad detectives said Nathan Barnwell, 45, of 940 Woodoak Dr. was arrested in the Saturday slaying of Winfield Gillespie, 39, of Pennsylvania on Barnwell's tree-lined residential street.

Barnwell is charged with first-degree manslaughter, two counts of second-degree criminal possession of a weapon and tampering with physical evidence -- a charge resulting, police said, from his hiding the gun from investigators after the shooting.
