The jury has already convicted Naeem Williams of murder and decided he is eligible for the death penalty.
In closing arguments Friday, Justice Department trial attorney Steven Mellin showed the jury autopsy pictures of five-year-old Talia.
Mellin says Williams has gone so beyond the bounds that he deserves the ultimate punishment and that he tortured his little girl and took steps to hide his actions.
Mellin also showed the jury a picture of Talia's empty room and said she didn't have a bed, blanket, toys, books, never got medical care or anything.
The government said that when Williams is in prison he will have a bed, blanket, medical care and access to a TV.
Defense attorney Michael Burt argued that Williams' crimes are horrible, but he was a good and decent person before and after the crime.
"He will be held captive for the rest of his life. He won't see light. That is the real punishment," said Burt. "It's not fair to give Naeem Williams the ultimate punishment when someday Delilah Williams will see the light of day. She certainly contributed in every way, shape or form to what happened."
Delilah was Talia's step mother. The government agreed to give her a 20-year prison term for her role in Talia's death.
