Up to eight marked Jeffco sheriff's vehicles, several unmarked police cars and a large SWAT vehicle were spotted Wednesday morning near the Indian Hills post office.
Witnesses saw several officers disembark from the SWAT vehicle after it had headed up Natsihi Road and stopped in the 2200 block.
An officer on Parmalee Gulch Road near the post office was guiding traffic around another large truck that was unloading.
Despite requests for information from the Courier, the Sheriff's Office would say only that deputies were assisting the Denver Police Department. The Denver department said it would not comment due to it being an ongoing investigation.
