Thursday marks one year since Mayor Ed Murray declared a homelessness state of emergency in Seattle.

Since then, 158 people have been housed through rapid rehousing and 125 households have been diverted from homelessness.

On Wednesday, Murray connected homelessness to the heroin problem.

"Those folks who are living in unauthorized encampments, literally probably 80 percent are addicted to opiates. And we know this heroin crisis continues to grow,” said Murray.

A new mobile medical van has served nearly 600 homeless patients, providing about half of them with mental health or chemical dependency assistance.
