The Latest on the stabbing attacks at a Massachusetts shopping mall and home that left two dead and saw the suspect fatally shot by an off-duty sheriff's deputy (all times local):

7:45 a.m.

Family members of the man who killed two people during a rampage in Massachusetts say he was mentally ill and has just been released from a hospital psychiatric ward.

Arthur DaRosa was shot and killed by an off-duty sheriff's deputy after fatally stabbing one person at the Silver City Galleria mall in Taunton on Tuesday, shortly after he stabbed an 80-year-old woman in her home.

Kerri Devries, DaRosa's sister, tells the Boston Herald her brother has been battling depression for years. She says he has recently been suicidal, and the "devil was playing tricks on him." She says he was admitted to the hospital Monday.

DaRosa's father, also Arthur DaRosa, tells the newspaper he was surprised when his son returned from the hospital Tuesday morning, but said he appeared "normal" and calm."

Authorities are trying to determine why a man went on a stabbing rampage in Massachusetts, killing two people and assaulting and stabbing more in a house and a shopping mall before being shot dead.

The suspect in Tuesday's attacks has been identified as 28-year-old Arthur DaRosa.

Authorities say it all began when DaRosa crashed a car outside of a house in the city. They say he walked inside the home and stabbed two women, including an 80-year-old who later died.

Authorities say DaRosa then drove to the Silver City Galleria mall, where he crashed into the front of Macy's department store. They say he assaulted multiple people inside the store before running to Bertucci's restaurant and stabbing two more people, including a 56-year-old man who died at a hospital.

An off-duty sheriff's deputy then fatally shot DaRosa.
