Both Burlington Township men are charged with murder.
Clemons also faces charges in a second violent incident against a service worker. He was charged last year with robbing, then beating a cab driver in Deptford in 2006.
Authorities are looking into whether the men might have been involved in other robberies. They're both being held on bail of $750,000.
The victim was a 50-year-old who sent money to his wife and six children in Bangladesh.
