Two men are dead and a woman is seriously injured following a brutal stabbing in a Brighton Beach home early this morning. The tabloids are claiming the incident was a murder/suicide.

Authorities say that cops were alerted to a stabbing at an apartment at Ocean View Avenue near Brighton 12th Street at around 2:34 a.m. yesterday. There, they found 59-year-old Voclodymyr Yeushchenko bleeding from a stab wound to his neck. He was declared dead at the scene. Outside the building, officers found 30-year-old Kostyantyn Proskurnyak, who was unconscious and unresponsive and had sustained severe body trauma. He was transported to Coney Island Hospital, where he was pronounced dead.

Later, police found a 29-year-old female at the corner of Brighton Beach Avenue and Coney Island Avenue, who had sustained stab wounds to her back, wrist, and forehead. She was transported to Lutheran Medical Center in stable condition.

The Daily News reports that Proskurnyak stabbed Yeushchenko, who was his stepfather, during a fight in the apartment. Proskurnyak also allegedly stabbed the 29-year-old, who is reportedly his sister, when she intervened. He then allegedly jumped off the building to take his own life.

The News reports that authorities recovered a knife, believed to be the murder weapon, at the scene. The NYPD says no arrests have been made, and the investigation is ongoing.
