AURORA, Colo. - Twelve crosses were lined up on an Aurora street corner on Monday to honour the 12 people killed three years ago in the shootings at a Colorado theatre.

People came throughout the day to see the crosses and write notes on heart cards attached to the crosses.

A jury last week convicted gunman James Holmes of killing the 12 people and wounding dozens more on July 20, 2012.

On Monday, attorneys began debating jury instructions for the death penalty phase of Holmes' trial.
