The Dane County Medical Examiner has released the identity of the man who police say went into his company's offices on Wednesday and shot four co-workers before authorities shot him with injuries that eventually took his life.
WISC-TV says Anthony Tong, 43, was the suspect.
He is believed to have lived on the 9700 block of Gilded Cider Boulevard. Police searched his property Wednesday.
Authorities say he worked for the company for 18 months, and Wisconsin court records showed no criminal history.
