RENO, Nev. (AP) — The head of Nevada’s Department of Corrections has resigned at the request of Gov. Steve Sisolak in the wake of an escape by a convicted bombmaker that went unnoticed for four days. Sisolak “requested and received Nevada Department of Corrections Director Charles Daniels’ resignation, effective immediately,” the governor’s office said in a statement Friday. Six other officers were placed on administrative leave. Porfirio Duarte-Herrera, 42, escaped from the Southern Desert Correctional Center outside Las Vegas on Sept. 23 without anyone noticing for four days, before a tip led to his capture at a transit center in Las Vegas on Wednesday night as he prepared to board a bus out of town.
