A huge party on Government Island in the Columbia River ended with a stabbing. The partiers had setup a makeshift stage for a DJ and powered the sound system with generators.

When police and sheriff's deputies arrived around 2 a.m. they had to move through the large crowd to find the stabbing victims.

The island is only accessible by boat, so police, paramedics and firefighters had to be taken from the south bank of the Columbia River to the island which is located near the I-205 bridge.

Three people are hospitalized.  One had serious injuries and the other two are in stable condition.

A suspect is in custody.
