BEAVERTON, Ore. -

A Vancouver man and his wife are accused of promoting prostitution, and the man faces additional charges for a police chase Tuesday that caused several crashes in Beaverton.

Police say they followed the couple after they dropped off a 17-year-old girl at a Beaverton hotel. When they tried to pull over the vehicle it sped off, hitting a couple of cars and crashing through fence. A semi-automatic military style rifle with ammunition was found in the vehicle.

The 21-year-old man tried to run off but a police dog found him hiding in a child's pink play house. He was booked into the Washington County jail on charges that include being a felon in possession of a firearm.

The 17-year-old girl was picked up as a victim of human trafficking.
