Peel regional police say an 88-year-old woman has died after she was attacked with a weapon Tuesday night in Mississauga.

Const. Akhil Mooken said investigators believe the attack was “isolated and targeted,” and they aren’t looking for any other suspects.

Police were called to a home in the area of Shelby Crescent and Willowbank Trail around 6:15 p.m. for reports of an assault.

Upon arrival, officers found the victim in life-threatening condition, suffering from blunt force injuries. She was rushed to a trauma centre but died in hospital. She has been identified Mariantonia Biunno.

It’s not yet clear what weapon was used in the attack.

Const. Mooken said the suspect, a 52-year-old man, surrendered to police and is in custody. Police later identified the suspect as Antonio Biunno, the victim’s son.

He appeared in court on Wednesday and has been charged with second-degree murder.
