A trial date has been set for Adrien Graham Wallace, 41, in the shooting deaths June 4 of his mother and nephew.

Wallace is scheduled to stand trial Oct 2, 2013, said Greg Horner of the Clackamas County's District Attorney's office. Wallace is accused of the aggravated murder of Saundra Sue Wallace, 71, and Nicolas Brian Juarez, 16, as they attempted to leave Saundra Wallace's home in the 18000 block of Indian Springs Circle.

The teenager from Mountain View, Calif., was visiting his grandmother. The incident took place near Childs Road, just outside the Lake Oswego city limits.

Wallace, who lived at the home with his mother, appeared at Monday's appearance at the Clackamas County Courthouse in Oregon City. He did not speak.

A potential bail hearing has been tentatively set for Aug. 21, Horton said. He remains in the Clackamas County Jail where he is being held without bail.

According to a document filed at the jail shortly after his arrest, Wallace, who is unemployed, confessed to shooting his family members "in the face" with a hunting rifle. About 40 law enforcement officers responded to the June 4 incident, including Lake Oswego police, Oregon State Police, Clackamas County deputies and personnel from the state medical examiner's office.
