TAUNTON, MA - Authorities have identified a man who they say killed two people and wounded four others in stabbing attacks at a home and a shopping mall in Massachusetts before being shot dead.

The Bristol County District Attorney's Office said Tuesday that 28-year-old Arthur Darosa crashed a car outside a home, walked inside and stabbed an 80-year-old woman and another woman. The 80-year-old was taken to a hospital, where she later died. The other woman is being treated for life-threatening injuries.

Authorities say Darosa then drove to the Silver City Galleria mall and crashed a car through the front of a Macy's store. They say he assaulted multiple people inside the store before walking to a restaurant and stabbing four people, including a 56-year-old man who later died.

Investigators say an off-duty sheriff's deputy fatally shot Darosa.
