A 17-year-old boy from Mexico City died of a hickey, Mexican media reported.
Julio Macias Gonzalez had a bruise on his neck, given to him by his 24-year-old girlfriend, according to Hoy Estado De Mexico.
He was at home with his family in the Iztapalapa borough when he began having strong convulsions.
Julio's relatives caused emergency services, but paramedics could not save him. They later attributed his death to the hickey on his neck.
They said the bruise caused a blood clot to form, which then traveled to his brain, causing a stroke.
