As a teenager growing up in New York City, John Mallett spent time in the juvenile wing of the jail on Rikers Island. He had stabbed a boy in a fight over a girl. As a young adult, Mallett, a paranoid schizophrenic, continued to have problems with the law. He served three years in prison for robbery. Mallett's family tried to get him help through the courts and public health, but were ignored. They learned that the criminal justice system is of no help to a family of a violent, mentally ill person until that person commits a heinous crime. Then, of course, it is too late.
In 2002, Mallett moved to Nashville, Tennessee where his mental illness continued to lead him into trouble. In March of that year, he was convicted of resisting arrest, and in July 2010, for criminal trespass. In February 2011, just before moving to Columbus, Ohio, the authorities in Nashville charged Mallett with the unlawful possession of a weapon. (That charge was later dismissed.)
In Columbus, Mallett moved in with his aunt. He became such a problem for her she asked him to move out. This may have placed the mentally ill man under considerable stress. On March 14, 2012, while in downtown Columbus a few blocks from the state capitol, Mallett entered the 25-story Continental Centre building carrying three knives, one of which came from his aunt's kitchen. The office building housed, on the first floor, a for-profit trade school (criminal justice, security, investigation, and court reporting) called Miami-Jacobs Career College. The school, owned by the Delta Career Education Corporation headquartered in Virginia Beach, Virginia, consisted of 37 campuses and 16,000 students around the country.
In the trade school's admissions office, Mallett, carrying a knife in each hand, repeatedly stabbed two employees and a criminal justice student. Back outside, he knifed an attorney who worked for the state attorney general's office, also housed in the building. Several bystanders tried but failed to disarm Mallett. One of the witnesses dialed 911.
Within minutes of the 911 call, Columbus patrol officer Deborah Ayers pulled up to the building. The 15-year veteran of the force confronted Mallett near the building's entrance. "Sir," she yelled, "you need to put the knife down. Sir, please put the knife down!" Instead of complying with the officer's command, Mallet lunged toward her with his knife. Ayers fired 11 shots at Mallet, hitting him several times. Before he collapsed to the pavement, a second officer shocked him with a stun gun.
The 37-year-old Mallett and his four victims were rushed to a local hospital. They were expected to survive their wounds. The fact Mallett lunged at the officer with the knife suggested a suicide-by-cop attempt.
On Thursday, March 15,2012, he day after the rampage, the local prosecutor charged John Mallett with four counts of felonious assault.
A battery of psychiatrists appointed by the court to examine Mallett concluded that he suffered from severe paranoid schizophrenia. On June 10, 2013, Franklin County Judge Kimberly Cocroft found Mallett not guilty by reason of insanity.
A few weeks after the verdict, corrections officials assigned the schizophrenic to a Columbus area forensic psychiatric facility where he was to remain incarcerated until his doctors declared he was sane enough to rejoin society.
