The Dallas County medical examiner identified the couple involved in an apparent murder-suicide at an Irving motel Friday as Juan and Dawn Castillo of Irving. Mrs. Castillo, 30, was shot about 1 p.m. inside the Budget Lodge at 110 W. Airport Freeway and died soon after.

Police engaged in a four-hour standoff at the motel with Mr. Castillo, 32, before finding him dead with a self-inflicted gunshot wound.
