A defendant accused of fatally shooting a man because he didn’t want to pay him for a drug deal pleaded not guilty in Brown County Circuit Court Monday.

Pedro Santiago-Marquez is charged with first-degree intentional homicide and being party to mutilating a corpse in connection with the Sept. 27 murder of Jason Mendez-Ramos.

Prosecutors say Mendez-Ramos was angry that he had not been paid $80,000 for a cocaine deal. A criminal complaint says rather than pay for the cocaine, Santiago-Marquez shot him in the head with a pistol. The victim’s burned body was found at the edge of the University of Wisconsin-Green Bay campus, WLUK-TV reported.

Security videos, cell phone tracking information, and DNA tie Rodriguez-Garcia to that scene, according to the criminal complaint.

Another man, 47-year-old Alexander Burgos-Mojica, is charged with harboring or aiding a felon in connection with the case. He returns to court March 18 for a balance of initial appearance. Rodriguez-Garcia returns to court March 21 for a status conference on the charge of mutilating a corpse.
