The last known address of John W. Mallett — the suspect in Wednesday's apparently random stabbing of four people at a Columbus, Ohio trade-school office — was an Antioch halfway house for people dealing with mental disorders or substance-abuse issues, WTVF is reporting.
According to reports, Mallett, 37, had lived in Columbus for the past month. But he'd previously lived in Nashville for a decade and had a police record here:
His criminal record dates back to March of 2000, when he was found guilty on one count of resisting arrest. In July of 2010, he was convicted of criminal trespassing.
In February of last year, Mallett was charged with unlawful possession of a weapon, but that charge was later dismissed.
The halfway house's director told WTVF that he had come a few months ago but stayed only a week before she asked him to leave, on grounds she felt he was "unstable" and a threat to other residents.
According to the report, Mallett's aunt told Columbus police that he was mentally ill and off his medications at the time of the attack. Mallett, who was brandishing multiple knives, was shot by police and is in critical condition, as are two of his victims.
