Abdulazeez had drug and alcohol problems, and his family tried to place him in a rehabilitation program. The New York Times reported that limits on the family's health insurance coverage "thwarted their plan to have him go into rehab." The investigation after the shooting revealed that Abdulazeez "had serious psychological problems." According to a family representative, Abdulazeez was abusing sleeping pills, opioids, painkillers, and marijuana along with alcohol. He had also been thousands of dollars in debt and was planning to file for bankruptcy. In 2012 or 2013, Abdulazeez began therapy for his drug and alcohol abuse. He had also received treatment for depression and often stopped taking his medication. Following the shootings, Abdulazeez's parents claimed that their son had been suffering from depression. According to a source that was provided by CNN, Abdulazeez was suffering from bipolar disorder.

It has been referenced that Fryberg has discussed killing himself before October, which could indicate that Fryberg was suffering from mental health issues well before this time.

30-round magazines; Lanza was carrying multiple high-capacity clips, reportedly enough
ammunition to kill nearly every student at school.
Adam Peter Lanza had Asperger's Syndrome, a disorder on the autism spectrum that makes social interaction difficult. Adam struggled with a sensory disorder from a young age. As Adam got older, he "was not open to therapy" and "did not want to talk about problems and didn’t even admit he had Asperger’s". However, the doctors who saw him didn't think he had a propensity for violence. Lanza’s mental health was also scrutinized after the shooting, and while his social isolation had been noted, we did not find evidence that concerns had been brought to the attention of a public authority.
Two 15-round magazines; Engeldinger fired at least 46 bullets during the shooting. At his home,
police recovered packaging for 10,000 rounds of ammunition.
Andrew Engeldinger's parents pushed him for two years to seek treatment for what they suspected was mental illness, but even though he became increasingly paranoid and experienced delusions, there was nothing more they could do. Engeldinger was never formally diagnosed with a mental illness, but his family was concerned enough by their son's behavior, which included claims that he was being followed, to enroll in a free, 12-week "Family to Family" course offered by the Minnesota National Alliance for loved ones of people with mental illness before he cut off contact in late 2010. His family suspected he had paranoid schizophrenia and two years before the shooting they reached out on his behalf to the National Alliance on Mental Illness.

None of that would have been enough to satisfy authorities that Page should be detained for a mental health evaluation for his own safety or the safety of others, Dunn said. But the suicide scare of 1997 would have been enough to alert Army doctors that Page had mental illness and was unfit for duty, said John Liebert, a psychiatrist who does fitness exams for the military and has written an academic text on suicidal mass murderers.

Alleged Aurora, Colo, shooter James Holmes met with not one, but at least three mental health professionals at the University of Colorado prior to the massacre. His name was brought to the attention of the university's Behavior Evaluation and Threat Assessment team or BETA for short. A flow chart released by the university shows guidelines for action that could be followed if a person is deemed a direct threat. While a student at the University of Colorado, Holmes was treated by the school psychiatrist, who expressed concern about his behavior and referred him to the university Behavioral Evaluation and Threat Assessment (BETA) team. They took no further action and he was never adjudicated mentally ill.

extra magazines and ammunition; 75 rounds fired
The Associated Press reports that the incident left the ex-Marine with post-traumatic-stress disorder. His ex-wife, who was a stylist at the salon, had claimed that her husband was unstable and physically abusive during their marriage and prior to the accident, according to the AP. Her friend Sharyn White told the AP that Michelle Fournier Dekraai said that her ex-husband had stopped by the salon weeks prior and threatened to kill her and the others at the salon. Though White said her friend told her that everyone else at the salon laughed off the threat, she took it seriously. Dekraai had been diagnosed with Post Traumatic Stress Disorder, and during a custody suit his ex-wife had filed court papers claiming that he was mentally unstable and had threatened to kill himself or someone else at least once.
|9/6/2011||Nevada||Carson City||Eduardo Sencion||32||Hispanic||Male||4||4||7||Resturant||No||Yes||Suicide||No||TBD||Yes||Yes|
20- and 30-round magazines; Police recovered 450 rounds of AK-47 ammunition from Sencion’s van and “box upon box” of additional ammunition at his home.
South Lake Tahoe police said the department took Sencion into protective custody during a mental health commitment in April 2000 and that he fought with officers. He was not charged. Sencion was taken into protective custody during a mental health commitment in April 2000 but no court order was involved and it remains unclear if a record of the incident was reported to the NICS database.
|1/8/2011||Arizona||Tucson||Jared Lee Loughner||22||White||Male||6||6||13||Other - Outdoors||#N/A||No||Caught or Surrendered||No||TBD||Yes||Yes|
The FBI said that Loughner had a second thirty-round magazine, and two standard mags (15 rounds apiece).
Interviews with Loughner's parents revealed they were deeply concerned about their son's increasingly angry and erratic behavior. His mother, Amy Loughner, said he no longer used alcohol and had tested negative for drugs. The papers also reveal Loughner did not seek mental health treatment. When he was expelled from college, his parents were urged to have him evaluated, but they never followed up. Loughner was rejected from enlisting in the Army in 2008 because he admitted he had used drugs. Loughner had a history of mental illness and drug use. He was rejected from Army enlistment in 2008 after failing a drug test and admitting to drug use on his U.S. Army medical history application form, which should have prohibited Loughner from buying a gun for at least one year.

During a court-ordered mental health evaluation, Clemmons told psychologists he had experienced hallucinations in May 2009 of "people drinking blood and people eating babies, and lawless on the streets, like people were cannibals". He claimed the visions had since passed. He also claimed to have no faith in the American justice system and thought he was being "maliciously persecuted because I'm black and they believe the police". The evaluation, completed by two psychologists from the Western State Hospital on October 19, concluded Clemmons was dangerous and presented an increased risk of future criminal acts. After a mental evaluation, a psychologist concluded Clemmons was competent to stand trial on the charges, which eliminated him as a candidate for involuntary commitment. An attorney for Clemmons notified the court he planned to pursue an insanity or diminished-capacity defense.

30- and 20-round magazines; Hasan fired at least 220 rounds of ammunition and has 200 rounds in his

30-round magazine; Allegedly fired 98 rounds during the attack. At least one magazine with a
30 round capacity was recovered at the scene.
Mr. Wong displayed no outward sign of mental illness. But it now appears that he was harboring a growing paranoia, with a fixation on law enforcement rooted in a few brief encounters that seemed to convince Mr. Wong that the police were out to do him in. Just before setting off on his massacre, he sent a two-page delusional rant to a Syracuse television station saying the police were spying on him, sneaking into his home and trying to get into car accidents with him. Nga said that she did not recognize the letter’s handwriting as being her brother’s, and that he had not told the familyabout his paranoia about the police. The letter might be a sign that he had “lost his rational thinking,” she said. People who knew Wong said he exhibited no outward signs of mental instability, although a letter he wrote that was delivered to a newspaper after the shooting indicated he was paranoid and suffering from mental illness.

Stewart's defense team argued that Stewart suffered from mental illness including depression and borderline personality disorder, and that he had been taking regular doses of the prescription sleep aid Ambien far in excess of the recommended limit. Combined with prescriptions for an antidepressant and anti-anxiety drug, they argued, it made Stewart essentially a lethal sleepwalker.

He was attending therapy sessions, taking medication and being hospitalized for depression by the time he was 6 years old. Throughout most of his life, he and his family were plagued by his psychiatric problems. The day after he turned 14, he was sent to a mental health treatment center for threatening to kill his stepmother Candace Hawkins with an axe. Four months later, he became a ward of the State of Nebraska, which lasted nearly four years. He had undergone two psychiatric hospitalizations, and was diagnosed with attention deficit disorder, an unspecified mood disorder, oppositional defiant disorder, and parent-child relationship problems. His extensive treatments cost the state USD$265,000.
