Jury selection began Monday in the trial of an Ohio teen charged in the shooting death of his identical twin brother during a robbery at their mother's house.

Nineteen-year-old Derris Lewis has pleaded not guilty to aggravated murder, aggravated robbery and kidnapping.

The twins' mother told police that several masked men entered her house and shot the older twin, Dennis, after holding her at gunpoint in January 2008.

Police in Columbus have said there is no evidence of multiple attackers. They say Lewis acted alone.

Defense attorney Adam Nemann has said three witnesses will testify that Lewis was on the other side of the city when the shooting happened.

Lewis faces a maximum of life in prison if convicted.
