OKLAHOMA CITY -- A murder suspect escaped the Oklahoma County jail in Oklahoma City early Friday by using sheets tied together to climb down the outside of the building from a 12th floor cell, authorities said.

Pablo Robledo, 34, who was being held on a first-degree murder charge, and his cellmate escaped by breaking a window of their cell and climbing down, according to jail spokesman Mac Mullings.
