The suspect in a Wisconsin workplace shooting that seriously injured three people this week had his concealed-carry permit revoked and was unable to legally purchase a firearm, police said Friday.
Middleton Police Chief Chuck Foulke said the gunman, 43-year-old Anthony Tong, had “contact” with police in South Dakota in 2004 that involved a mental health issue. Foulke didn’t give details of the South Dakota incident, but he cautioned against concluding that mental health was an issue in Wednesday’s shooting at WTS Paradigm in Middleton.
Foulke said police still don’t know what motivated the attack . Tong, who had worked at the company since April 2017 and had no criminal history in the state, was fatally shot by police responding to the incident.
Authorities also said Friday that the conditions of three workers seriously injured had improved. The woman and two men have been upgraded from serious to fair condition at University Hospital in Madison, according to UW Health. A fourth employee suffered a graze wound during the attack. Their names haven’t been released.
Police don’t know if the victims were targeted or shot at random.
