Ohio dentist murders gun match a 'big problem' for surgeon ex: Defense attorney

A preliminary ballistic match linking a gun recovered from Michael McKee's Illinois property to the scene of a double homicide of an Ohio dentist and his wife marks a "big problem for him and his defense team," according to legal experts.

McKee, 39, a Chicago-area vascular surgeon, faces two counts of premeditated aggravated murder in the Dec. 30 shooting deaths of his ex-wife, Monique Tepe, 39, and her husband, Spencer Tepe, 37.
