Suspect arrested after 3 killed in Idaho shooting spree

Investigators are probing the background of a suspect in a shooting spree in Moscow, Idaho, that left three people dead and another critically wounded.

A gunman opened fire Saturday at three separate locations in the western Idaho city, killing a victim at each site.

John Lee, 29, the suspected attacker, was captured in the afternoon following a high-speed chase in nearby Washington state.

Moscow Police Chief David Duke said Lee killed his adoptive mother, 61-year-old Terri Grzebielski, at her home before heading to Northwest Mutual life insurance.

The gunman shot David Trail, 76, a Moscow businessman, and Michael Chin, 39, of Seattle. Trail died at Pullman Regional Hospital. Chin was treated for critical wounds at Moscow hospital before being flown to a Seattle hospital, Duke said.

Upon leaving the insurance office, the shooter drove to an Arby's restaurant and asked for the manager. When she appeared, he pulled out a gun and opened fire. The manager, 47-year-old Belinda Niebuhr, died at the Moscow hospital.

Duke said that Trail, the brother of a former Idaho state representative, was Lee's landlord. He said there were "some issues" regarding the apartment, but didn't know of any eviction proceeding.

Chin had no link to Lee but was discussing business with Trail when the gunman arrived. Duke said Chin was shot in the arm and leg.

Investigators were trying to determine if there were any links between Lee and the Arby's manager.
