An arraignment for a suspected serial killer is postponed because a judge orders the suspect to undergo a mental evaluation.
Investigators in Pulaski County say Michael Abner confessed to killing three people over a 30-year span.
Abner is charged with killing his neighbor, Jack Roerink, 79, back in January.
Police say Abner then confessed to killing two elderly women in the 1980s.
Abner will be back in court on April 15th, at that point prosecutors say they'll file a motion to make the case a death penalty one.
