A Bronx man has pleaded guilty to manslaughter and criminal sex act in the death of a 15-year-old girl.

Luis Vega, 38, faces 25 years in prison for killing 15-year-old Destiny Sanchez in November 2012.

Sanchez's body was found in the lobby of a building on Barretto Street in Hunts Point.

The medical examiner says she was strangled and suffered compression injuries to her neck.

Police say Vega gave Sanchez alcohol the night of the incident, and her body was found with bleach poured on her the following morning.

Vega is the brother of Sanchez's stepmother.

He is set to be sentenced May 20.
