22-year-old Elliot Rodger killed six people and injured fourteen others by gunshot, stabbing and vehicle-ramming near the campus of the University of California, Santa Barbara (UCSB) before fatally shooting himself.

In the document, Rodger described his childhood, family conflicts, frustration over his inability to find a girlfriend, his hatred of women, his contempt for couples, and his plans for "retribution".

[1][2] Rodger faced mental health problems as a child; he struggled in social situations, often cried in crowds, and displayed repetitive behaviors.

[15][16][17] He intended to steal their car and drive it back to Isla Vista, targeting the Alpha Phi sorority house with plans to kill its occupants before setting it on fire.

[27][28][29] Denizens of these forums, including Rodger, identified themselves as "involuntary celibates" or "incels"; they discussed their difficulties with finding a romantic or sexual partner, and expressed disdain towards women and pick-up artists.

[3][4][5] Rodger moved Wang's body to the corner of a bedroom, threw it face-down on the floor, and partially covering it with blankets, towels, and clothing.

[b] In the video, Rodger said he was frustrated at remaining a virgin at 22, that he would "punish" women for rejecting him despite being an "alpha male" and a "Supreme Gentleman", and expressed his hatred for sexually active men.

[3][5][54] After driving away from the sorority house, Rodger executed a three-point turn in a driveway along Pardall Road and discharged a shot toward a closed coffee shop.

[h] 20-year-old Christopher "Chris" Michaels-Martinez, who was at the deli's entrance, was shot once in the chest when he turned around to look at Rodger's car, resulting in injuries to his liver and the right ventricle of his heart.

[99] During his attack, Rodger killed six people, all of whom were University of California, Santa Barbara, students, and injured fourteen others—seven by gunfire and seven whom he hit with his vehicle.

[185][186][187] As they separately approached Isla Vista, Li Chin called Rodger's apartment building manager, asking them to check if her son was in his room.

[93][193] In Rodger's room, which was messy, police found pharmacy documents for prescriptions, two gun cleaning kits, empty ammunition boxes and magazines, energy drinks, lottery tickets, a copy of The Art of Seduction by Robert Greene, video games, and a Starbucks coffee cup.

Police also discovered two journals in which Rodger expressed his growing frustration at his inability to form relationships with women, a hand-drawn illustration of a stabbing, and a printed version of his 137-page manifesto.

[42][200] In June 2014, his body was cremated and released from the coroner's office to his family, who held a private ceremony and planned to hold a funeral in England later that year.

[208][209][210] In interviews with the Daily Mail and Kent Online, Rodger's paternal grandmother described him as "very sick" and a "disturbed boy", mentioning that if her husband was still alive, he would be in "terrible shock".

Peter said his son was good at hiding his true emotions, expressed sorrow for the pain caused to the victims' families, and said he would help prevent future mass killings.

She later began participating in threat assessment training sessions, sharing her experiences and hoping people will find warning signs of individuals in mental distress.

"[ad] On April 23, 2018, 25-year-old Alek Minassian killed eleven people and injured fifteen others in Toronto, Canada, by driving a van into pedestrians.

Williams objected to Rodger being labeled the "virgin killer", saying that implies "one possible cause of male aggression is a lack of female sexual acquiescence".

[324] Film critic Ann Hornaday of The Washington Post attributed the attacks to Hollywood's "sexist movie monoculture", which she said is largely produced by white men.

[331][332][333][334] Sheriff Bill Brown said Rodger's actions and copycat attacks were due to shortcomings in the mental-health treatment system, noted a widespread shortfall in resources for community mental health care, and criticized inadequate communication from healthcare professionals regarding people who suffer from suicidal or homicidal thoughts.

[344][345][346] Subsequently, the Sheriff's Office concluded the responding deputies followed all rules and conducted themselves professionally in accordance with both state law and departmental guidelines.

[371][372][373] Santa Barbara Assembly members Das Williams and Nancy Skinner introduced legislation that would allow law enforcement, close relatives, or roommates to request a court order for the confiscation of firearms from individuals deemed a serious risk to themselves or others.

[380][381][382] Williams' and Skinner's bill passed through both legislative chambers but was opposed by the NRA and other groups advocating for Second Amendment rights, and launched statewide robocall campaigns against it.

[389][390][391] In March 2015, Hong's, Wang's, and Chen's parents filed a wrongful death lawsuit in federal court against Santa Barbara County, the Sheriff's department, Capri Apartments, and the property management company, claiming negligence and breaches of the victims' constitutional right to due process.

[403] In June 2015, the parents of Cooper filed a wrongful death lawsuit against Santa Barbara County and UCSB, claiming that there were failures in mandatory responsibilities as well as negligent hiring and training of deputies.

In October 2015, Judge Colleen Stern determined that the lawsuit did not meet the required legal standards to proceed but allowed them to submit a revised complaint by November 10 of that year.

Cooper's parents' lawyer told Noozhawk they believed the judge's ruling was largely influenced by the legal safeguards that protect government entities from being sued for the choices made by police.

[134][405][406] The lawsuit alleged both campus police and the Santa Barbara Sheriff's Department did not adequately investigate Rodger despite his release of several YouTube videos indicating his potential threat to others.

[417][418] Originally slated for release in October 2015,[419][420] because Del Playa faced significant backlash, Hart decided to push the film back.
