A typical xray of a drug mule who ingested drugs.

Nigerian man dies after drugs burst in his stomach!
This is a chilling and sad story.Reading it gave me the creeps,imagine a man cutting his own stomach open with a glass?He must have been really possessed and in serious agony to free himself of the drugs ingested into his body.
The 25 year old Nigerian man identified as Austin Chukwuna died on Sunday May 31st after the hard drugs he was smuggling out of Indonesia burst inside his stomach. According to Indonesian Police, Chukwuna had on Saturday May 30th lodged at a hotel close to the Soekarno-Hatta International Airport Indonesia possibly with the intent of flying
out with the drugs inside him, when he suddenly ran out of the hotel on Sunday morning, screaming. Witnesses saw him run to the hotel car park like a lunatic, broke the glass of one of the cars and used it to cut himself as he tried to get the drug out of his system.

"Austin Chukwuna, 25, ran out of the Ibis Hotel near the airport compound where he had just stayed a night. He allegedly tore open his abdomen with pieces of glass," Benda Police chief Comr. Heddi Managsi said

Why would you swallow all of this and risk your life?

The police chief said when they searched inside his hotel room, they found three methamphetamine capsules and another eight meth capsules on the highway. "We then took him in the ambulance, but he died on the way to Tangerang General Hospital," he said.
Why do these Nigerian drug mules keep endangering their lives? Is it strictly cos of lack of opportunity,employment,greed,or all of the above?
