Police on Wednesday identified a man killed this weekend in east Charlotte as Oscar Alvarado Chavez, 22.

Chavez was stabbed to death Sunday afternoon in his car behind the Advenir Apartments on Central Avenue near North Sharon Amity Road. Police said a man and woman met him to buy heroin, but robbed and killed him instead.

Jonathan Fitzgerald, 18, and Danielle Holmes, 17, were charged with the killing after they were arrested that night in Cabarrus County. They're being held in Mecklenburg County Jail without bond.

Court records show Chavez has been previously charged with only traffic offenses in North Carolina.
