A human arm that washed up onto a dog park at Montrose Beach in Chicago on Tuesday afternoon could be that of slain Elgin woman Gail S. Peck, according to reports.
The Chicago Sun-Times has reported that detectives are working to determine whether the arm belongs to Peck, 76, whose son has been charged with killing her.
The limb was discovered about 11 a.m. Tuesday near Montrose Beach in the 500 block of West Lawrence, according to Chicago Police, ABC 7 News reported.
Authorities have said that Brian M. Peck, 55, told police he knocked down Gail Peck during an argument over loud Jimi Hendrix music, stomped on her head and used a handsaw to cut up her body in the house they shared. Some of her remains were found Oct. 28 in suitcases weighed down by paver bricks in a lagoon in Chicago's Lincoln Park.
The killing is said to have happened in the early morning hours of Oct. 25. Two days later, Brian Peck called 911 to report his mother missing.
Brian Peck now faces two counts of first-degree murder and one count of concealing a homicide.
