Omaha Police Chief Todd Schmaderer said 40-year-old Dr. Anthony Garcia was arrested Monday in Illinois.

Schmaderer says Garcia acted alone in the murders of 65-year-old Roger Brumback and 65-year-old Mary Brumback near 114th and Shirley and the 2008 stabbing deaths of 11-year-old Thomas Hunter and his family housekeeper, 57-year-old Shirlee Sherman.

Both Roger Brumback and Thomas Hunter's father worked in Creighton's pathology department. Schmaderer says Brumback and Hunter fired Garcia in 2001 when he was a pathology resident for erratic behavior.

Schmaderer declined to discuss details of the evidence against Garcia who currently lives in Terre Haute, Indiana.  He says Garcia showed signs of alcohol impairment and had a gun when he was pulled over by Indiana State Troopers Monday morning.
