NORMAN — An estranged husband shot and killed his wife's divorce attorney late Tuesday night before driving across town where he shot and killed his wife and set her home on fire.

Hours later, Timothy Michael Deffner, 55, shot and killed himself in rural Pottawatomie County as law officers closed in on him, officials said.

The sequence of events began about 11 p.m. Tuesday when police received two 911 calls reporting homicides. Police say Deffner kicked in the front door of the home of attorney Bryan Young in the 700 block of Trisha Lane.

Police responding to the home a short time later found Young, 47, suffering from several gunshot wounds. Young, a former Norman North High School principal and soccer coach, was taken to a hospital, where he later died.
