Video at link: http://www.turnto10.com/news/6368285/detail.html NBC 10's Kelley McGee reported that Victor Cortez's arraignment on a murder charge was postponed Monday so a public defender could be appointed. The arraignment was rescheduled for next week. Cortez is serving time at the Adult Correctional Institutions for first-degree armed robbery. Police said that before his arrest for that crime, he killed 25-year-old Yodit Kaleab. Investigators said they linked Cortez to Kaleab's killing through bodily fluids and physical evidence... Kaleab's body was found in a minivan parked between the Providence train station and the State House in October. She had been reported missing about a week earlier.
