BOULDER COUNTY - The man accused of starting a shootout with a deputy earlier this month died Sunday.
Adrian Shaffer, 37, was listed in grave, critical condition after authorities say he shot at Deputy Teri Javes on Sept. 10.
According to the Boulder County Sheriff's Office, Shaffer was seen walking along Highway 287 near Longmont shirtless and agitated. 911 callers said he was trying to "pick fights" with passing traffic. He was also reported to have a handgun in his waistband.

Javes caught up with Shaffer just a few miles from where 911 callers reported seeing him. He reportedly then started shooting at Javes as soon as she got out of her patrol car. She wasn't hit, but the driver's side window in her patrol car was shot out.
Shaffer was hit twice and was taken to Longmont United Hospital by ambulance and later airlifted to a Denver hospital for further treatment.
The sheriff's office was told Shaffer died overnight Sunday.
The investigation into the attempted murder of Javes, and the resulting officer-involved shooting, remain under investigation by the Boulder County Investigation Team.
