A somber police motorcade carried a slain deputy's body away from the scene of a bloody rampage Wednesday as investigators tried to determine what set off a shooting and stabbing spree that left six people dead and four wounded.

The mother of suspect Isaac Zamora, who was released from jail less than a month ago, said he is "desperately mentally ill" and had been living in the woods. Dennise Zamora said one of those killed Tuesday was a sheriff's deputy who had tried to help their family for years.

Isaac Zamora, 28, was being held Wednesday on suspicion of first-degree murder and attempted first-degree murder and is being held on $5 million bail.

The shootings began close to Dennise Zamora's house near the small town of Alger, about 70 miles north of Seattle. They continued amid a high-speed police pursuit on Interstate 5 and ended in Mount Vernon, about 20 miles south of Alger, when Isaac Zamora surrendered at a sheriff's office.

"Some of these are just random shootings," Trooper Keith Leary said.

A motorcade escorted a hearse bearing the body of Skagit County Deputy Sheriff Anne Jackson, 40, on Wednesday from Alger to a funeral home in Mount Vernon. Dozens of police cars and motorcycles joined in.

County court records show Zamora has a history of petty violence and theft, including one case in 2003 in which he was charged with biting the hand of an employee of a drug treatment center. That case was dismissed.

A host of questions remained unanswered Wednesday, including whether the suspect knew any of the victims, how the shootings apparently continued during the police chase and how Zamora managed to turn himself in rather than being arrested by one of the many officers pursuing him.

There are eight crime scenes being investigated by more than 100 people from 15 agencies, Leary said Wednesday.

"We're not speculating as to what happened," Leary said. "It's too early to tell what took place at each scene."
