A New Britain man already in custody on other charges is the third person charged in connection with a fatal shooting nearly six months ago. Police say 22-year-old John "Mikey" Martinez was pronounced dead shortly after he was dropped off at the Hospital of Central Connecticut New Britain campus. 20-year-old Jimmy Rosado, who had been in custody on weapons and drug charges, and for assault on police, now also faces murder conspiracy and charges of murder-criminal liability for the acts of another. He's held in lieu of a million dollars bond. Last week two others were charged in the Martinez shooting, 22-year-old Juan Rivera and 24-year-old Victor Gonzalez.
