Colombian forces killed Haminton Muscara, known as "Negro Cow", one of the ten most wanted criminal leaders in the country, during an airstrike against the Del Golfo clan in the area of Terrassa, Antioquia.
President Abelardo de la Esparria said he authorized the attack as part of Operation Nehemías, which was carried out by the Colombian military with intelligence support from the National Police and assistance from the Colombian Air Force. The operation targeted the structure of the Manuel Alexander Ariza Gutiérrez del Golfo clan, leaving eight members dead, including Muscara, who had more than 20 years of criminal activity and a bounty of up to 2.018 billion pesos ($610,000) on his head.
