BOSTON - Two men killed a cocaine dealer to avoid paying a debt, dismembered his body and cooked the remains at a concrete business, prosecutors said.

Daniel Bradley, 47, of Westwood, and Paul Moccia, 48, of Dedham, pleaded not guilty yesterday in Wrentham District Court to murder charges in the death of Angel Antonio Ramirez, a construction worker from Guatemala who lived in Framingham.

Moccia met Ramirez near the concrete company in Walpole that Bradley co-owns and shot him in the back with a .357-caliber pistol, said Norfolk Assistant District Attorney Robert Nelson.

Moccia owed Ramirez $70,000 from drug deals and decided to kill him instead of paying up, authorities said.

Bradley dismembered the man's remains and then tried to get rid of the evidence once and for all, Nelson said.

"It was cooked," he said.

Prosecutors didn't say how they arrived at their theory, or how the body was cooked or disposed of.

Defense attorneys said that their clients are innocent and noted that prosecutors haven't produced a body.

Investigators found blood spots inside the concrete business, RJ Bradley Co. Inc., Nelson said, as well as on a pair of Bradley's boots at his Westwood home.

Bradley is an assistant football coach at Xaverian Brothers High School. Moccia is a Massachusetts turnpike-toll collector. Both were held without bail. *
