HARI SREENIVASAN: In the day’s other news, investigators around Des Moines, Iowa, are looking for a motive in the ambush killings of two policemen early today.

The 46-year-old suspect, Scott Michael Greene, was arrested hours later. Authorities say both officers were sitting in their police cars when they were shot to death. The killings happened less than two miles apart.

SGT. PAUL PARIZEK, Des Moines Police Department: What we can tell by looking at the scene is that it doesn’t appear that either officer had an opportunity to interact with the suspect. It doesn’t look like there was an exchange of conversation. It doesn’t look like there was an opportunity — there definitely wasn’t an opportunity for these officers to defend themselves and respond to the attack.

HARI SREENIVASAN: Police say they believe the gunman acted alone.

They pointed to a series of scandals, including spending millions in state funds on Zuma’s rural home.
