OMAHA, Neb. —
"We didn't feel this individual would stop unless an arrest was made," Schmaderer said.
Schmaderer said the task force investigating this case is in the process of searching several places where Garcia lived since 2001, but officers believe he acted alone.
The attacks happened in Omaha neighborhoods where homicides are rare. The city averages about 40 per year.
One of the Brumbacks' three children, Darryl, said the family had no comment about the arrest. A male relative of Sherman's also declined to speak. The Hunter family didn't respond to a phone message seeking comment.
The attack in which Hunter's son, Thomas Hunter, and housekeeper, Shirlee Sherman, were killed at the family's 3,700-square-foot home in the historic neighborhood of Dundee was featured last year on "America's Most Wanted," and a $54,000 reward was offered. Some of Omaha's most prominent residents live in the neighborhood, including billionaire investor Warren Buffett.
Schmaderer said Monday that investigators don't believe the boy and the housekeeper were the intended targets of the attack.
Authorities have released few details about the attack on the Brumbacks, other than manner in which they were killed. Their bodies were discovered in their west Omaha home on May 14.
The task force was set up after the Brumbacks' deaths to investigate whether they were tied to the unsolved 2008 killings. Schmaderer declined to say what led investigators to Garcia.
