ICE has filed a detainer on Volodymyr Zhukovskyy, 23, who is charged with killing seven bikers Friday in New Hampshire.

That means the West Springfield truck driver faces being deported back to his native Ukraine if and when he is released. Zhukovskyy pleaded not guilty today to negligent homicide. A judge ordered him held.

An Immigration and Customs Enforcement official told the Herald the detainer has been filed with the sheriffs in New Hampshire.

Deportation proceedings usually come after a suspect has served time on any state charges.

Zhukovskyy’s father told the Herald Monday his son had just secured a U.S. green card.

“I’m sorry for the families,” the defendant’s father, also named Volodymyr Zhukovskyy, added.

The father said they are from the Ukraine and his son recently got permanent resident status in the United States.
