A Port Jefferson teenager was arraigned in court on Sunday after allegedly killing a man in his town.

Investigators say 19-year-old Joseph Garcia was the gunman who pulled the trigger at around 3:30 p.m. Wednesday, killing 25-year-old David Bliss Jr. on Main Street.

Garcia was charged with second-degree murder.

Defense attorney George Duncan says Garcia denies the allegations, and he says the shooting may have happened in self-defense.

The judge ordered Garcia to be held without bail.

If convicted, Garcia faces a possible sentence of 25 years to life. He will be back in court on April 1.
