Two brothers accused of killing another man after a woman allegedly hired them to kill her husband pleaded not guilty to all charges Monday in Montgomery County Court. 27-year-old Delia Hernandez-Cortes of Collingdale in Delaware County, 21-year-old Gabriel Martinez-Lopez and his 26-year-old brother Jose Miguel Martinez-Lopez, both of King of Prussia, all face first degree murder charges in the beating death of 32-year-old Jose Cazares-Olarte in early April in King of Prussia. Prosecutors say a statement Gabriel Lopez gave police indicates the murder was planned for at least three weeks before the victim was smashed in the head with a landscaper’s paver brick while he knelt at gunpoint. The district attorney’s office is seeking the death penalty for the men, but not the woman. Hernandez allegedly dated Gabriel while working for a short time at the La Poblanita Mexican Bar in Norristown, where he also worked. All three are illegal Mexican immigrants who had been deported at least once in the past. The victim was also in the country illegally.
