Authorities say a fifth person has died following a shooting at a shopping mall north of Seattle.

A spokesman for the Skagit County Emergency Operations Center says the unidentified male victim died early Saturday at a Seattle hospital. Four female victims died earlier following the Friday night shooting at the Cascade Mall in Burlington, Washington.

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.
