The suspects recently arrested in connection with the cold case disappearance and death of a Georgia woman nearly four years ago allegedly tricked her son into thinking she was still alive after she died nearly four years ago.
Matilde Gonzalez, 43, was last seen in Cobb County on Oct. 11, 2019 and her family reported her missing a day later, the Cobb County Police Department said last week.
At the time of her disappearance, investigators suspected foul play.

The case went cold but on Sept. 8, authorities made a "significant breakthrough" that led to the arrest of Alejandra Castro, 41; Abel Castro, 45; and 20-year-old Samantha Vasquez after authorities searched a home in Paulding County.
Alejandra Castro and Vasquez are charged with malice murder. The Castros are also charged with concealing a death and cruelty to children.
In a warrant obtained by 11 Alive, authorities said Gonzalez was killed during a fight at a Cobb County home and then the Castros got rid of her body.
To conceal the killing, the suspects allegedly fooled Gonzalez's son into thinking his mother was still alive by having someone pretending to be her and contacting him through a Mexican phone number, local media reported.
