Former Nebraska lab worker arrested for four killings

A former Nebraska pathology lab worker and doctoral student has been arrested as a possible suspect in two double homicides, deaths which may be linked to the medical school he attended before he was fired for erratic behavior in 2001. 

Anthony Joseph Garcia, 40, was arrested in Illinois Monday for the murders of 65-year-old Roger and Mary Brumback, committed in May, as well as for the 2008 deaths of 11-year-old Thomas Hunter and family housekeeper Shirlee Sherman.

Roger Brumback and the father of Thomas Hunter both worked in the pathology department that Garcia was fired from in 2001, apparantly after he displayed "erratic behavior," according to the Associated Press. 

Omaha police Chief Todd Schmaderer told Omaha.com that Garcia fits "the elements of a serial killer," adding: "We did not feel this individual would stop unless an arrest was made." 

"These cases put Omaha neighborhoods and the Creighton University medical staff on alert for the last five years. Tonight, you can be confident the Omaha Police Department never forgot about this case," commented Omaha Mayor Jean Stothert, in the Omaha.com report. 

Garcia was arrested on four counts of first-degree murder, said CNN.

Brumback had recently retired from his role as a professor in the pathology and neurology departments at Creighton University in Omaha.

At the time of his arrest, he had a .45 handgun on his person. 

In the May murder, the killer appears to have shot Roger Brumback dead and stabbed his wife Mary, according to Omaha.com.
