According to the arrest affidavit, Johnson would swaddle Cedric to restrict his movement and that the 27-year-old did it one time because the child made a mess with ketchup packets.

The affidavit stated that on July 10, Cedric was swaddled and began to throw up before becoming unresponsive. Johnson admitted to dumping the 18-month-old’s body in the trash.

According to Cedric’s aunt, she woke up during the night he went missing and found that both the child and Johnson were gone from the northeast Dallas apartment.

Johnson was arrested and charged with injury to a child causing serious bodily injury. He may face more charges as the investigation continues.
