Dandeny Muñoz Mosquera (born August 27, 1966), also known as "La Quica" (Colombian slang for "the fat girl", a childhood nickname), is a Colombian former hitman for the Medellín Cartel, a drug trafficking group. He was described as at one point being the "chief assassin" for the Cartel's leader Pablo Escobar. He was believed to be responsible for the deaths of an unknown number of people with official estimates ranging in the hundreds. US authorities currently link him to the deaths of more than 220 people, having supposedly murdered members of both his own organization the Medellín Cartel and the rival Cali Cartel, as well as police officers and government officials. Colombian authorities connect him to the deaths of more than 40 police officers. Arrested in 1991, he is serving multiple life sentences in a US prison. He was the first person ever to be convicted under a 1956 Federal law that made bombing a civilian aircraft a crime and the 1986 terrorism statute that allows the trial of foreign citizens in the United States if at least one victim was an American citizen. Among his convicted crimes is the 1989 bombing of Avianca Flight 203, which killed 110 civilians. Early life Born in Medellin, Muñoz Mosquera's father was a police officer and his mother an evangelist. He was raised in the church. He is believed to have joined the Medellín Cartel in 1978 at the age of twelve after being drawn into the gang by his brother Brance (also known as Tyson due to his resemblance to boxer Mike Tyson) before becoming a gunman in his teens. He was given the nickname "La Quica" (Colombian slang for "the fat girl") from a young age due to his resemblance to his great-aunt. He rose to become one of Pablo Escobar's highest ranking enforcers. However, Muñoz Mosquera has claimed that he joined the Colombian army as a teenager before leaving in 1986 and was jailed on "three or four" occasions on minor theft charges. In 1989, he was arrested and convicted of being one of the main conspirators in the assassination of New Liberalism founder Luis Carlos Galán, a candidate in the Colombian presidential election set to be held in May 1990. Galán was murdered by an unknown gunman as he took the stage at a political rally to deliver a campaign speech in Soacha. He was jailed in the capital
