DES MOINES, Iowa -

An Iowa man charged in the killings of two police officers was facing intense money problems, had been found by a judge to hit and financially exploit his mother and was ordered to move out of her basement hours before the shootings.

Forty-six-year-old Scott Michael Greene was arrested Thursday afternoon after detectives questioned him at the Des Moines police station. Greene was secured with the handcuffs that had belonged to the patrolmen who were killed in ambush-style attacks, Des Moines Sgt. Anthony Beminio and Urbandale officer Justin Martin, and was later booked into the county jail.

Greene was charged with two counts of first-degree murder. If convicted, he would receive an automatic sentence of life in prison without parole.
