Christopher Halford, 27, of Middle Park Road, Dudley, and a 16-year-old boy, who cannot be named for legal reasons, were charged early this morning with the 19-year-old's death.
Harvey was found with a stab wound to his back in Spring Pool Meadow in Russells Hall just before 7pm on Monday.
Despite the best efforts of the emergency services and neighbours, he was sadly pronounced dead at the scene.
Halford and the 16-year-old appeared before Wolverhampton Magistrates' Court on Saturday. They were both remanded into custody to appear before Wolverhampton Crown Court on Tuesday.
It means police have now charged four people with Harvey's murder.
Connor Oakley, 18, from Spring Pool Meadow, and a 16-year-old boy, who cannot be named for legal reasons, remain in custody after appearing at Wolverhampton Magistrates' Court on Thursday.
