Summary: A report was received regarding a person down on the northbound first on-ramp to northbound Interstate 880 in Santa Clara County, California. The incident was initially treated as a police (PD) man-down call, but there was uncertainty about a medical component as the reporting party noted the individual did not appear lucid. Fire and police units responded, but the person was not located by police within their jurisdiction, and the case was referred to the California Highway Patrol (CHP) as the location was on the on-ramp. Ultimately, the area was checked and no individual was found, leading to the cancellation of the response.
