. Benjamin was a bank robber who was arrested in Arizona in 1960 when Stephen was seven years old. Benjamin was later convicted and escaped prison in 1969, subsequently appearing on the
FBI's most-wanted list.
According to Stephen's brother Eric, "he (Benjamin Paddock) was never with my mom" and "we didn't grow up under his influence". After Benjamin was arrested, their mother told the children that their father had died in a car accident and kept his status as a bank robber a secret from the family.
Dolores proceeded to move her sons to the

, where Stephen spent his remaining childhood and adolescence in a low-income household. Dolores worked as a secretary to support the family. According to one of Paddock's ex-wives in a police interview, he had spoken about how growing up with a single mother and the family's financial instability caused him to prioritize being self-reliant and self-sustaining.
Another one of Stephen's brothers, Patrick Paddock II said that he and his brothers all grew up with anger, but he said he thought Stephen seemed the least affected. "My brother was the most boring one in the family," Patrick said of Stephen. "He was the least violent one."
Former high school classmates describe the younger Paddock as a "math genius" and "quiet and withdrawn".
Paddock attended Richard E. Byrd Middle School,
Sun Valley High School, and
John H. Francis Polytechnic High School, where he graduated in 1971. He went on to graduate from

Paddock meticulously planned the attack.[
] On September25, six days before the shooting, he checked into the hotel with 10shooting-range bags and a computer.[

On September 29, he moved into an additional suite, 32–134, connected to the first one; both rooms overlooked the festival grounds. He stayed in both in the days leading up to the shooting.[ After Paddock killed himself, the police found 23rifles and one handgun inside his rooms.][

] All fourteen AR-15-type rifles were outfitted with bump stocks that make the act of using recoil to assist in pulling the trigger again easier and faster, increasing the weapon's rate of fire.[ Audio recordings of the attack indicated Paddock used these stocks to fire at the crowd in rapid succession.][

At some point during the attack on concertgoers, Paddock – who had placed a webcamera on a service cart outside his room – fired about 35rounds through his door. The shots wounded approaching hotel security guard Jesus Campos. The unarmed Campos had attempted to enter the 32ndfloor first at 9:59pm on an unrelated matter but he found the door to the hallway screwed shut by Paddock.[

] At 10:05pm, Paddock began firing hundreds of rounds in rapid succession at the crowd below. He initially started off with a few single gunshots before firing in prolonged bursts. He stopped shooting ten minutes later at 10:15pm. It is speculated that at that time Paddock committed suicide, shooting himself through the mouth.
According to the chronology of events established by the authorities in the following days, the first two police officers reached the 32nd floor of the hotel at 10:17pm. A minute later, they were shown the location of Paddock's door. Between 10:26 and 10:30pm, an additional eight LVMPD officers joined them and began clearing other suites along the 32ndfloor hallway. At 10:55pm, eight SWAT team members entered the 32nd floor through the second stairwell nearest to Paddock's suite.[
] Once all the other rooms on the floor had been cleared, at 11:20pm — more than an hour after the first two officers arrived[

Investigation
In addition to the firearms and accessories found in Paddock's hotel room, there was a note that included handwritten calculations about where he needed to aim to maximize his accuracy.[
