Pleasant Valley resident Christian Walcyzk has pleaded guilty to manslaughter for the stabbing death in May last year of Daniel Siino, a 28-year-old father who lived in Hartsdale. Before the plea, he was facing charges that also included criminal impersonation and criminal possession of a weapon.

Shortly before 10:30 p.m. on May 27 last year, Siino and his wife were driving southbound on the parkway in their SUV when they encountered Walcyzk, who was heading in the same direction in his BMW. During the ride, Walcyzk pulled in front of Siino and slammed on his brakes, forcing Siino to follow suit, according to a statement announcing the plea deal released late Monday afternoon by Westchester County District Attorney Anthony A. Scarpino.

Siino attempted to pass Walcyzk, but the 22-year-old would not allow it, the statement said. The two men pulled their cars onto the shoulder of the Taconic State Parkway near the Briarcliff Manor exit in Mount Pleasant. 

Siino got out of his car to confront Walcyzk, who also got out, brandishing a fake police badge and a concealed knife behind his back, Scarpino said.

The two got in each others’ faces and Walcyzk stabbed Siino twice in the chest, accidentally slicing his finger in the process, according to Scarpino. Siino got back into his car, and told his wife he had been stabbed. She helped him into the passenger seat, pulled away and called 911. Siino died farther down the parkway when his wife eventually pulled over.

Walcyzk drove off and also called 911, claiming he had been the victim of a stabbing, according to Scarpino. He was located and transported to a local hospital, where he was treated for his injury. Further investigation led to his arrest, and he was transported to the New York State Police barracks in Hawthorne for booking.

Following his arrest, Walcyzk was indicted by a Westchester County Grand Jury in October. Walcyzk is scheduled to be sentenced on Nov. 14, when he will face up to 25 years in prison.
