A 12-person jury was seated Tuesday morning in the first-degree murder trial of Richard McTear, Jr. Opening statements began a short time later and ended shortly before noon.
Testimony began just after 1 p.m.
McTear, who is now 26, is charged in the death of 3-month-old Emanuel Murray.
The baby was found dead in May 2009, along Interstate 275 near Fowler Avenue. Police say McTear threw the baby from a car window.
McTear argued with the child's mother, Jasmine Bedwell, earlier that morning, investigators said. During the argument, he allegedly threw the child to the ground, then grabbed the infant and drove off with him.

A mistrial was declared in August 2013, after the victim's mother used inflammatory statements during her testimony.
If convicted, McTear could get the death penalty.
The slow process of jury selection, which included some 200 potential jurors, began July 15.
The trial could last three to four weeks, according to Judge William Fuente.
