Timeline suggests attack could’ve been thwarted as late as 6 minutes before shots fired
A comprehensive timeline of the attempted assassination suggests the ingredients were there to have potentially thwarted the attack as late as six minutes before the first shot was fired.
The timeline, reviewed by ABC News, said a member of a local SWAT team from Beaver County, Pennsylvania, first spotted the suspect, Thomas Matthew Crooks, at 5:10 p.m. Saturday -- about one hour before the shooting -- when he walked by a window. The team was comprised of eight snipers and spotters and had been in position since 10:30 a.m.
At 5:14 p.m., a member of the Beaver County sniper team took Crooks’ photo.
At 5:28 p.m., he took a photo of a bicycle and backpack.
At 5:32 p.m., a sniper saw Crooks looking at news feeds on his phone and noticed he had a range finder. The sniper flagged the suspicious activity in a group text and received a response saying, "Call into command." The sniper did as instructed at 5:41 p.m. and communicated a description of the suspect lurking around the AGR Building, the roof of which Crooks ultimately used as a perch.
At about 6 p.m., police sought information about the suspect’s direction of travel. At 6:05 p.m., Crooks was spotted at picnic tables carrying a backpack, and that information was relayed over the radio.
At 6:05 p.m., Trump walked onto the stage.
At 6:06 p.m., the sniper who first noticed Crooks left his position and went to meet patrol officers to let them know the suspect was around the building on the side of the fairgrounds. One marked vehicle and an unmarked vehicle moved into position.
At 6:12 p.m., shots were fired.
Police climbed onto the roof and confirmed the suspect dead at 6:32 p.m. A search of Crooks’ pockets turned up a phone and a transmitter device.
The timeline does not reveal who received the information and whether concerns a suspicious person and possible threat were transmitted to Secret Service commanders on site, who could have delayed Trump’s entry into the rally or opted to take additional security steps.

Fire truck carries body of firefighter killed at rally
The body of Corey Comperatore, the firefighter who was killed at Saturday’s rally while shielding his family from the gunfire, was transported on a fire truck for his funeral in Pennsylvania on Friday.
His fellow firefighters came together to carry his casket.
Comperatore, 50, leaves behind a wife and two daughters.
"Corey Comperatore was our beloved father and husband, and a friend to so many throughout the Butler region," the family said in a statement on Thursday. "He was a local leader and veteran, a former fire chief, and a committed Christian who found peace and joy through our church.”
"We thank the countless people who have prayed for us throughout the past week," the family added.
More information arises about shooter’s searches, including bomb-making
Thomas Matthew Crooks, the 20-year-old suspected gunman, actively searched about bomb-making, the date of Trump’s rally and about the Democratic National Convention, according to a source with direct knowledge.
He also actively searched for information about "major depressive disorder," the source said.
Crooks’ phone also contained some information about Oxford, Michigan, high shooter Ethan Crumbley and his parents, the source said.
Crooks’ phone contained images of FBI Director Christopher Wray, Attorney General Merrick Garland and other public figures, the source said.

Secret Service director will testify before House Oversight Committee Monday
Secret Service Director Kimberly Cheatle will testify on Monday before the House Oversight Committee, according to agency spokesman Anthony Gugliemi.
"The Secret Service is fully accountable for the safety of its protectees," Gugliemi said in a statement. "We are committed to better understanding what happened before, during, and after the assassination attempt of former President Trump to ensure it never happens again. That includes complete cooperation with Congress, the FBI, and other relevant investigations."
In the days since the attack, Cheatle and the Secret Service have faced heightening scrutiny for failing to prevent the incident from happening, and even calls from some for Cheatle to resign. Cheatle said she would not resign from her role.
