The Star Tribune reported that among those in critical condition were director of operations John Souter and production manager Eric Rivers.
Heather Buckingham, who lives near the office, told KARE 11 that she used to work at the company as a receptionist, and was familiar with the gunman - as well as his victims.
She said: 'It’s insane, it’s crazy. I know the guy, I know all the people.'
She told the station that the shooter had been fired from the company earlier in the day, and described him as a 'kind of odd' man who 'kept to himself.'

Marques Jones, 18, of Minneapolis, said he was outside a building down the street having his picture taken when he and his photographer heard gunfire that sounded close.
'We heard about four to five gunshots,' Jones said. 'We were shocked at what happened and we just looked at each other. We all just took off running to our vehicles.'
Hours before the shooting, Rahamim was interviewed by Star Tribune journalist Todd Nelson for a story about his company.

The company employed 28 people as of July, according to a feature on the business in Finance & Commerce, a local business publication. It was founded by Rahamim in 1984.
The paper reported that U.S. Under Secretary of Commerce Francisco Sanchez visited it in August in a trip focused on exporting and praised the company for its innovation.
The company developed a patented technology for producing signs in Braille and had licensed the technology to companies in 38 countries, the newspaper said.
Minneapolis Mayor R.T. Rybak said employees who were working when the shootings occurred were together and being cared for Thursday evening.
'We are deeply sorry about what has happened here,' he said, calling the shootings 'a horrible tragedy.'
