• The man who sped a rental truck down a riverfront bike path in New York on Tuesday had been planning the attack for a year and “appears to have followed almost to a T the instructions that ISIS has put out,” a city police official said. A second man was being sought.

Witnesses described the rampage as gruesome, grisly and surreal.

The suspect was identified as Sayfullo Saipov, a 29-year-old native of Uzbekistan, which is considered a militant breeding ground. He was living legally in the U.S., but some close to him saw signs of trouble.
