A 13-year-old boy has been arrested after allegedly murdering a man and wounding his wife in the couple's rural home.

Michael Thomas Burns was taken into custody Friday at Viewridge Middle School, hours after Jay B. Kennedy, 43, was shot to death.His wife, Kimberly Kennedy, suffered five bullet wounds and was in serious condition Saturday at Legacy Emanuel Hospital in Portland, Ore., officials said.

"It's horrifying," said sheriff's department spokeswoman Sgt. Peg Prather. "We all think of where we were at 13."

Kimberly Kennedy's two children - a 7-year-old boy and a 9-year-old girl - were not harmed.

According to authorities, Harper has confessed to shooting both adults with a gun he'd stolen in the couple's garage.

Clark County deputy prosecutor Dennis Hunter said Burns was an acquaintance of the victims but he would not elaborate on a possible motive.
