Karlo P. Maquinto (8 July 1990 – 3 February 2012) was a super flyweight Filipino boxer who resided in Baguio, Benguet, Philippines. He died after he collapsed at the end of his 7th professional bout.
Maquinto was born in Lambunao, Iloilo, the fifth of six children of Felicibar Jr. and Marjorie Maquinto. He completed his elementary education, but left high school to pursue his boxing career.
He collapsed after the end of an 8-round bout with Marc Joseph Costa in Caloocan, Philippines. The match had ended with a majority draw, the sole blemish on an earlier perfect 8-0-0 record with 6 KOs.[1]
Maquinto was rushed to FEU Hospital in Quezon City. He was diagnosed with subdural hematoma (bleeding on the brain).[2] Tests showed that a blood clot had developed in his brain as a result of blows received in the first round of the fight. Maquinto went into a coma; he died five days later in the hospital.
