Two dead in Cal Anderson Park in apparent murder-suicide

Two people died in Seattle's Cal Anderson Park Wednesday night in what appears to be a murder-suicide.

Seattle Police say it started when officers were called to the park about 8 p.m. and found a woman unconscious. They tried to save her, but she died at the scene.

The man they believe killed her took off and barricaded himself in a nearby water pump building. 

Negotiators tried to talk him out, but eventually they went into the building around midnight and found the man dead at the bottom of a huge tank that holds a water and bleach solution. 

The two were reportedly living together in a tent community in the park and were in some kind of relationship.
