CHICAGO (AP) — A suburban Chicago man has been convicted in the 2017 slaying and dismemberment of his mother, whose partial remains were found in a Chicago lagoon.

A Cook County jury deliberated about 21/2 hours on Tuesday before finding 59-year-old Brian Peck of Elgin guilty of first-degree murder, dismembering a human body and concealing a homicide death.
The Daily Herald of Arlington Heights reports Peck testified Monday that he killed his 76-year-old mother, Gail Peck, in self-defense in October, 2017, when she came at him with a knife after becoming annoyed at him for playing loud music.
Some of her remains were later found in a lagoon at Chicago's Lincoln Park.
