Police: Escaped felon Alberto Morales may still be in shackles DALLAS, Feb. 13 (UPI) -- A convicted rapist who escaped in Texas as he was being transported to Nevada may still be in handcuffs and shackles, investigators said late Tuesday. His chains were not found near the Dallas-area Walmart where Alberto Morales stabbed a Florida police officer and fled, The Dallas Morning News reported. Morales, 42, was being returned to Nevada to serve a sentence of 30 years to life. He had been transferred to Florida for legal proceedings that added another 10-year prison term, to be served if he is ever released by Nevada. "This is an extremely dangerous individual, and he's capable of anything," Sgt. Robert Eberling of the Grapevine Police Department said. If anyone knows of co-workers in Grapevine who didn't show up to work today, we want to hear about it. Two Miami police officers escorted Morales to Houston by plane. Investigators said he began hitting his head on the seat in front of him and after the plane landed the airline said he could not fly the next leg of the trip. The officers decided to continue to Carson City, Nev., in a rented SUV and arranged for a third officer to fly to Dallas to join them. On their way to Dallas/Fort Worth International Airport, they visited the Walmart in Grapevine, where one went into the store. Morales, with his hands shackled to a bellychain, somehow managed to stab Miami Detective Jaime Pardinas, 54, after breaking off the earpiece to his glasses. Pardinas was reported to be in serious condition after surgery at Parkland Memorial Hospital.
