FRANKLIN SQUARE - Police say that a cab driver from Queens was stabbed to death in Franklin Square last night during an argument over a fare.

Investigators say they believe William Mena, 32, was killed by fellow driver Christopher Heron during a disagreement about who would pick up the fare.

The victim's family tells News 12 Long Island that the fare that caused the fight amounted to $4.

Mena, who drove for Ollie's Taxi company, was pronounced dead at the scene. His family says he had two sons, ages 2 and 6.

Heron, also a Queens resident, was arrested and charged with second-degree murder, according to authorities.
