Man pleads not guilty in fatal stabbing on Taconic Parkway

A man accused of stabbing another man to death along the Taconic Parkway in May pleaded not guilty Thursday in Westchester County court.
Officials say 21-year-old Christian Walczyk has been charged with criminal impersonation, first-degree manslaughter and fourth-degree criminal possession of a weapon after allegedly stabbing 28-year-old Daniel Siino, of Hartsdale.
They say the incident allegedly happened because of road rage. 
According to police, Walczyk allegedly showed a fake badge while concealing a knife behind his back when he approached the victim before stabbing him twice in the chest.
The victim’s family says they are frustrated and angry at the defenses' not guilty plea.
"It's terrible, it's disgusting and it's just a sad thing that something like this had to happen over words," says Joe Siino, the victim’s father. "Everyone be careful on the road and be careful of people like that guy."
The family says Siino's wife was in the car at the time and will be a witness. Walczyk signed an order of protection Thursday stating he will not contact her in any way.
Walczyk is currently being held in Westchester County jail without bail.
