Shortly after midnight on Monday, February 26, 2018, a dark blue Dodge Neon was found parked on the 700 block of Chain Street in Norristown, Pennsylvania, with two men inside who had been shot in the head. The driver, 53-year-old Isaias Martinez, was pronounced dead at the scene; his passenger, 44-year-old Guillermo Rivera-Rubio, was taken to Einstein Hospital and died shortly after arrival. The Montgomery County Coroner’s Office ruled both deaths homicides from a single gunshot wound each.

Investigators concluded the shootings occurred during a cocaine transaction. Within two days authorities arrested 20-year-old Miguel Mino-Rojas of Norristown; police say he arranged to buy cocaine from the men and fired after he thought one reached into the glove compartment. A .45-caliber Pietta Colt revolver was recovered and identified as the murder weapon. Mino-Rojas was charged with two counts of first-degree murder, firearms offenses, denied bail, and remanded pending a preliminary hearing.

Did anyone in Norristown see the Neon or the men on Chain Street that night, or have information about the transaction?
