From Phoenix's Arizona Republic of April 5, 2004:
Man shoots, kills his neighbor
An off-duty state Department of Corrections employee fatally shot a neighbor who was suspected of beating a woman early Sunday.
Thomas Alfredo Keefe, 33, told police he saw Sergio Bustamante, 22, kicking his girlfriend in the head outside the couple's home in the 5700 block of West Glenrosa Avenue about 1:15 a.m., Phoenix Sgt. Bill Wren said.
Keefe, who was armed with a handgun, confronted Bustamante to stop the assault, Wren said. Keefe told him to stop and Bustamante grabbed a gun from his truck, Wren said.
Bustamante fired at Keefe, hitting him in the arm, Wren said.
Keefe returned fire, hitting Bustamante in the chest. Bustamante was declared dead at St. Joseph's Hospital and Medical Center.
Police did not release the woman's name but said she is in her late teens and lived with Bustamante. Her condition was unavailable.
Keefe was taken to St. Joseph's hospital for treatment. Details about his condition were unavailable Sunday.
Wren confirmed that Keefe is an employee with the Department of Corrections but said he does not know what Keefe does for the department. A DOC spokeswoman was unavailable for comment.
The incident is under investigation, Wren said.
