OMAHA, Neb. (AP) _ A Nebraska judge says an Indiana doctor accused of killing four people with ties to an Omaha medical school must remain in jail to await trial.
 
  Judge Lawrence Barrett ruled Tuesday morning that no bond would be set for Dr. Anthony Garcia.
 
  Garcia, of Terre Haute, Ind., was arrested in Illinois last week and extradited to a jail in Omaha.
 
  He is accused of shooting to death Creighton University pathologist Roger Brumback and fatally stabbing Brumback's wife, Mary, in May at the Brumbacks' Omaha home. Garcia is also accused in the fatal stabbings of 11-year-old Thomas Hunter and his family's housekeeper, Shirlee Sherman, in March 2008, also in Omaha.
 
  Brumback and Thomas Hunter's father fired Garcia from a Creighton residency program in 2001.
