A dishwasher allegedly opened fire on his co-workers — fatally shooting one and wounding another — inside a Delaware Avenue restaurant, as employees prepared to open for business Saturday morning.

The victims were a father and his son.

Rick Costner Jr., 18, a sous chef at Merge restaurant, 439 Delaware Ave., was killed, Buffalo police said.

His father, Rick Sr., 40, general manager of the restaurant, was taken to the hospital, and listed in stable condition Saturday night.

Arrested was the gunman, a 51-year-old Buffalo man who has been working as a dishwasher at Merge since May.

Ernesto Arechavaleta-Taureaux, a resident of Porter Avenue on the city’s West Side, has been charged with second-degree murder, attempted second-degree murder and criminal possession of a weapon.

He was scheduled to be arraigned in City Court this morning.

Chief of Detectives Dennis Richards would not comment on the motive for the attack, other than to say it was a case of workplace violence, part of a disturbing trend seen throughout the nation.

“It’s this kind of new phenomenon now in the workplace where there’s this lone gunman exhibiting violent behavior,” Richards said. “We’ve seen many instances of this in American culture.”
