A group of men were in the middle of the dispute on Tuesday, July 23, in a driveway on South Sixth Avenue, during which time Mount Vernon resident Tyfan Deans, 37, allegedly stabbed two men, Westchester County District Attorney Anthony Scarpino, Jr., said.

The two stab victims were transported to a local hospital for treatment, Scarpino said. Their conditions were not immediately available.

Scarpino said that at some point, Deans’ brother, Peter Thomas, who is a Westchester County Corrections Officer, arrived at the scene and fired a pistol into the air near the group. 

When members of the Mount Vernon Police Department arrived at the scene, Thomas turned over the weapon. A knife was also recovered at the scene.

Thomas and Dean, both of Mount Vernon, were arraigned in Mount Vernon City Court on Wednesday, July 24. Thomas was charged with reckless endangerment, while Deans was charged with two counts of assault, all felonies.

Following their arraignment, Thomas was released on his own recognizance, and bail was set for Deans at $1,000 bond or $500 cash bail. No return court dates have been announced for either suspect.
