A 30-year-old man jumped to his death after fatally stabbing his 59-year-old father and wounding his pregnant sister at their Brooklyn apartment, police sources say.
Konstyantyn Proskurnyak and Voclodymyr Yeushchenko were both pronounced dead after the violent family altercation at their apartment on Ocean View Avenue in Brighton Beach at about 2:30 a.m. Tuesday, police say.
Sources say Proskurnyak stabbed Yeushchenko, who is his father, in the neck at the apartment. He then turned his weapon on his 29-year-old sister, who is 17 weeks pregnant, when she walked in on the grisly scene.
The sister then ran out of the apartment and called 911, sources say, while Proskurnyak ended his assault and jumped out of a window.
When police and EMS workers arrived at the scene, they found Yeushchenko dead in the apartment.
Officers looked alongside the building and found Proskurnyak on the ground and unconscious. He was taken to Coney Island Hospital, where he was pronounced dead.
Proskurnyak’s sister was taken to the hospital with stab wounds to her back, wrist and forehead. She is expected to recover from her injuries, and her baby was uninjured.
