MEMPHIS, Tenn. -- The defense for a man charged with murdering his 3-year-old son wants to prove it was all just a terrible accident.
Maurice Brown is charged with killing his son, Maurice Brown, Jr., in July 2012.
The defense claims Brown never meant to kill Junior and just spanked him too hard.
But Brown reported the boy missing and cried in front of WREG cameras, asking for his safe return.
The boy's body was found in a dumpster days later.
The prosecution and defense argued about what could have caused the boy's fatal injuries.
The medical examiner used graphic autopsy photos and diagrams to show injuries to Junior's body. She said he bled to death internally from a laceration to the liver. He also had numerous bruises, broken ribs and bleeding on the brain.
The defense tried to convince the jury that Junior got some of the injuries from the spanking, and some from running around the apartment and hurting himself.
It's a theory the prosecution found impossible, especially after asking the chief medical examiner.
The medical examiner said Junior couldn't have caused the fatal injuries himself.
Brown may still take the stand in his own defense when court resumes Saturday morning at 8:30.
If found guilty, he faces life in prison.
