Colorado mass shooting suspect faces 43 additional charges

The big picture: The new charges include additional attempted murder, assault and weapons charges, per the Colorado Sun. The suspect, 22-year-old Al Aliwi Alissa, was already charged with 10 counts of first-degree murder and one count of attempted murder.

• While possession of high-capacity magazines is illegal in Colorado, it's not yet clear if the suspect bought them illegally.
• They could have been legally bought in other states, or as AP notes, "people in Colorado can still buy the parts for the magazines at some gun stores and assemble them on their own, at which point it is illegal to possess them."
• Authorities have said Alissa legally purchased a Ruger AR-556 pistol used in the attack.

Our thought bubble, via Axios' John Frank: Despite the new details, the most pressing question remains unanswered: Why? Boulder prosecutors said authorities still don’t know why the gunman targeted that store, located about 20 minutes from his home in Arvada.
