It all stemmed from the murder of 70-year-old Hilda Gonzalez, who was allegedly suffocated by her daughter, Sasha Gonzalez.

According to a police report, Sasha Gonzalez killed her mother because of an argument about Castillo not leaving the home.

Police said Sasha Gonzalez removed the doorknob from her mother’s locked bedroom door so she and Castillo could suffocate her by putting a large black trash bag over her head.

According to the police report, Sasha Gonzalez, her boyfriend, Yancel Castillo, and Santy Castillo put the body on a pile of tree branches on the side of the house and set it on fire the morning after the murder. The remains were then put into county trash bin.
