"I kill for God. I listen to God," a man accused of a northwest Washington shooting rampage said Friday at a hearing where six charges of first-degree murder and four of first-degree assault were filed against him.

Isaac Zamora made the chilling comment twice at the brief hearing in Skagit County District Court while investigators wrapped up their work at eight crime scenes. The 28-year-old is being held on $5 million bail in the wake of Tuesday's rampage, which left six people dead and four injured.

District Court Judge Warren Gilbert read each charge and the penalties, which carry a maximum sentence of life in prison. That doesn't mean the death penalty is off the table, according to the Skagit County prosecutor.

"Do you talk about it? Sure you talk about it," Prosecutor Rich Weyrich told the Skagit Valley Herald. "Where it goes, it's way too early to decide that."

Zamora was not required to enter a plea Friday. The charges filed in District Court allow Zamora to be held in custody for 30 days. He will later be formally charged in county Superior Court.
