NEW YORK — An Islamic extremist who killed eight people with a speeding truck in a 2017 rampage on a popular New York City bike path was convicted Thursday of federal crimes and could face the death penalty.

Sayfullo Saipov bowed his head as he heard the verdict in a Manhattan courtroom just a few blocks from where the attack ended. Prosecutors said the Halloween rampage was inspired by his reverence for the Islamic State militant group.

The dozen jurors deliberated for about seven hours over two days before convicting Saipov, 34, of 28 counts of crimes that include murder in aid of racketeering and supporting a foreign terrorist organization. Jurors will return to court no earlier than Feb. 6 to hear more evidence to help them decide whether he should be executed or spend the rest of his life in prison.

A death sentence for Saipov, a citizen of Uzbekistan, would be an extreme rarity in New York. The state no longer has capital punishment and the last state execution was in 1963. A federal jury in New York has not rendered a death sentence that withstood legal appeals in decades, with the last execution in 1954.

Even before the trial, there was no doubt Saipov was a killer.

His lawyers conceded to the jury that he rented a pickup truck near his New Jersey home, steered it onto the path along the Hudson River and mowed down bicyclists for blocks before crashing into a school bus near the World Trade Center.

He emerged from his truck yelling “God is great,” in Arabic, with pellet and paintball guns in his hands before he was shot by a police officer who thought they were real firearms.

The vehicle attack killed a woman visiting from Belgium with her family, five friends from Argentina and two Americans. It left others with permanent injuries, including a woman who lost her legs.

“His actions were senseless, horrific, and there’s no justification for them,” defense attorney David Patton told the jury during the trial.

The defense asked jurors to acquit Saipov of racketeering charges, saying he intended to die a martyr and was not conspiring with the Islamic State organization, despite voluminous amounts of propaganda from the group found on his electronic devices and at his home.
