Bryan gave investigators written consent to search the house.
Search warrants filed this week show that DNA samples were taken from Rebecca Bryan, and her husband's cellphone was among items taken from the home.
Bryan filed for divorce in January 2010, but the couple were living together in the house at the time of his death.
On her way out of the courtroom Friday, Bryan waved to her son.
James said her other son, Trent Bryan, is an El Reno firefighter who was unable to attend the hearing. Both sons have been supportive of their mother and have visited her in jail, James said.
“She's got a very good family,” he said.
