LAS VEGAS (AP) — Amateur artist Michael Eramdjian (RAHM'-john) was working on a watercolor image at a memorial to 58 people killed in a shooting last year at a Las Vegas Strip country music festival when he reflected on the shooting deaths of 12 people this week at a country music bar in Thousand Oaks, California.

The 82-year-old Eramdjian called it very sad and said Friday he has to wonder what goes through the mind of mass shooting assailants.

Social media organizers planned a Friday evening vigil at the downtown Las Vegas Community Healing Garden to show sorrow and solidarity with family and friends of those killed at the Borderline Bar & Grill.

A sign attached anonymously to a remembrance wall already marked the Thousand Oaks tragedy.

"12 Angels Gone Too Soon," it says.
