The Puerto Rican boxer Félix Verdejo Sánchez turned himself in to law enforcement officials on the island on Sunday evening and is facing charges of killing a pregnant woman whose body washed up in a lagoon on Saturday, the authorities said.
According to a federal complaint, Mr. Verdejo, a lightweight boxer who represented Puerto Rico at the 2012 Olympic Games in London, is accused of punching the woman, injecting her with “substances,” tying her body to a block and throwing her from a bridge into the water.
The woman, Keishla Rodríguez Ortiz, disappeared on Friday.
