DENVER (KDVR) — Monday night a man went on a shooting spree across Denver and Lakewood, during which he killed a total of five people.

One of those victims was Michael Swinyard, 67, who was killed where he lived in the 1200 block of N. Williams Street, just outside Cheesman Park.

According to a letter to tenants that FOX31 obtained, the suspect forced himself into Swinyard’s apartment while a security guard called 911.

In addition to Swinyard, the shooter killed three people at area tattoo shops and one employee at an extended-stay hotel in Belmar.
