Boulder police have closed 16th Street between Spruce and Pearl streets after an officer found a person dead in a parked car from an apparent suicide, dispatchers said.
Dispatchers said at around 12:30 p.m. they received a medical call and an officer who responded saw a person dead inside a parked car near 16th and Pearl. Dispatchers said the death appears to be a suicide, but did not elaborate.
"We don't know if circumstances are suspicious or what exactly happened," police spokeswoman Kim Kobel added later.
Boulder hazardous materials crews also were called to the scene.
"There are chemicals in the car, and we wanted to err on the side of caution," Kobel said.
