In the days since the brazen Oct. 23 daylight ax attack on NYPD cops, investigators have pieced together the final days and weeks in the life in attacker Zale Thompson, 32, who was shot and killed by police defending themselves.

Two sources briefed on the case tell ABC News that Thompson’s history paints the picture of a man consumed by jihadi philosophy and a desire to attack U.S. government and authority figures, egged on by the brazen attack on Canada’s parliament a day before.

“As of last Thursday, detectives had found 277 sites he visited within last nine months that had something to do with al Qaeda, ISIS, beheadings or jihad,” said one police source. “He’s been all over the charts.”

About five days before the attack, Thompson locked himself in a room in his father’s home, where he did little but view jihadi websites until his father threw him out on Oct. 21, police sources said.

“The guy was angry at authority, angry at the establishment,” one source said. “And so he’s in there basically getting hypnotized by the computer. Talk about brainwashing. This guy sat in his room for days at least three days straight, closed the door and just sat in front of his computer.”
