The Pueblo County Sheriff's Office reports some new evidence has led them to a second suspect in a recent murder.
Clay Eldred was shot to death earlier this week during a run in with security at the American Iron and Metal Plant.
Deputies arrested plant security guard Ronald Lee Galvan Friday.
Investigators believe Galvan and their first suspect, David Noriega, tampered with evidence at the scene. Officials reported Friday statements given by Noriega and Galvan were inconsistent with evidence found at the scene.
Galvan was arrested on accessory charges to murder and booked with a $150,000 bond.
