TORONTO — Faisal Hussain, the gunman who staged a deadly rampage in Toronto this summer, had four cellphones in his bedroom and another on him. The police found what appeared to be cocaine in a drawer under his bed. And while Mr. Hussain stood over a woman and shot her four times, he waved a man in his path away, casually saying, “Don’t worry, I’m not going to shoot you.”

These are a few of the details revealed in three police requests for search warrants that were unsealed by a Toronto judge on Thursday.

Mr. Hussain, 29, shattered the calm of a July night, opening fire on a busy Toronto street and sending diners in restaurants and packed patios scurrying for cover. He continued his shooting spree as he walked, aiming at people enjoying the summer evening. By the time he exchanged gunfire with the police and shot himself in the head, he’d killed two people and injured 13 more.

While the police documents paint a clearer picture of the terror Mr. Hussain caused that night, and the lonely life he lived, they leave many important questions unanswered: What was Mr. Hussain’s motive. And was he was connected to others?
