Omar Thornton, minutes after gunning down eight co-workers in Manchester, Connecticut, called state police and told them, "I took it into my hands" because he worked at a "racist place," according to a recording of the call.
Thornton, 34, told police, "I wish I could have got more of the people." He also said, "I'm not going to kill anybody else."
The Hartford Distributors employee fatally shot himself Tuesday after the shooting spree that followed his resignation over theft allegations.
The gripping recording of Thornton's four-minute 911 call was released Thursday, the same day the company said he never filed a complaint alleging racial discrimination, as his girlfriend Kristi Hannah asserted.
