(A-P) An Iowa construction company says the man suspected of killing two Iowa police officers was hired last month but quit days later. Police say Scott Greene turned himself in just hours after the two officers were fatally shot in separate ambush attacks early Wednesday. Sara Nicklin, the office manager for Central Iowa Fencing in Ankeny, said Greene “was pretty desperate” to find work and told the company he had a teenage daughter to support.

Nicklin says Greene was hired even though he had no experience building fences. She says he was sent home on his third day “because he was not taking directions and wasn’t working,” and when told he could work on a different crew, “he chose not to show up.” Greene posted a cellphone video online last week indicating he was fired after reporting unsafe driving. Nicklin denies Greene was fired and says she hasn’t seen the video.

No formal charges have been filed yet against Greene, but he man remains hospitalized. Des Moines Police Sgt. Paul Parizek says Greene remained in a hospital Thursday morning for treatment of an existing medical condition.
