Guzman escapes from the Altiplano maximum security prison through a 1.5 km (1 mile) tunnel from a hole in the shower area of his cell. The hole is ten meters (yards) deep and connects with a tunnel that is 1.7 meters (yards) high that is fully ventilated and has lighting, supposedly built without the knowledge of the authorities. Authorities find a motorcycle adapted to run on rails that they believe was used to carry dirt out and tools in during the construction. The tunnel terminates in a half-built house in a rural farm field near the prison.
Guzman is last seen at 9:00 p.m. A manhunt has begun, with roads being patrolled by federal police with many checkpoints and a Blackhawk helicopter flying overhead. Flights from Toluca airport near the prison are suspended and the hangars are being searched. A Guatemalan special task force of police and soldier are watching their border with Mexico.
