The fate of Naeem Williams is now in the hands of the jury.
Williams is charged with the murder of his five-year-old daughter at Wheeler Army Airfield in July 2005. If convicted, he could face the death penalty under federal law.
Prosecution and defense attorneys presented closing arguments during a day-long session in federal court.
Prosecutor Steve Mellin questioned the testimony presented by several defense medical witnesses who said it may not have been a head injury that killed Talia Williams.
Meanwhile, defense attorney John Philipsborn spent two hours attacking the credibility of Williams’ wife, Delilah, who testified against her husband.
Delilha Williams is serving a 20-year prison term under a plea agreement with the government.
Williams was serving in the Army at the time of his daughter’s death.
