A fifth person has died following a shooting at a US shopping mall 60 miles north of Seattle.
The unidentified male victim died this morning at a Seattle hospital after a gunman opened fire at the Cascade Mall in Burlington, Washington state.
Authorities are continuing to search for the shooter.
Four other victims, all female, died following the incident on Friday night.
A Washington State Patrol spokesman said officers are seeking a Hispanic man wearing black and armed with a "hunting-type" rifle, last seen walking towards the Interstate 5 motorway.
Authorities say the motive for the shooting is unknown at present.
