As of 8:05pm this situation is active, be careful out there, stay away from the scene, and let law enforcement do their job.
From scanner traffic is seems that the subject might now be on foot, police are repeatedly asking for a clothing description. K9 units have been requested.
The Ukiah PD began the chase near Talmadge Rd. in Ukiah, and then pursue at extreme speeds of over 110 miles per hour. The California Highway Patrol took over, and it seems that Willits PD is also involved.
Apparently a request was put in for the Sonoma County Sheriff's helicopter (CalFire does fly at night). It is unclear if that copter was the one heard earlier tonight.
