Authorities continue to search for the shooter. A Washington State Patrol spokesman says police were seeking a Hispanic man wearing black and armed with a “hunting-type” rifle last seen walking toward Interstate 5. Authorities say the motive was unknown for the shooting about 60 miles (97 kilometers) north of Seattle.
