DALLAS — A Dallas man is accused of killing his roommate on Sunday night in Oak Cliff, according to an arrest warrant affidavit.
Gilbert Martinez, 39, faces a murder charge in the killing of Christopher Rubio after the pair was involved in a disagreement about 7:30 p.m. at a home in the 2700 block of West 12th Street.
A neighbor reported hearing people arguing and hearing a “pop," the affidavit said. Another neighbor said he saw Martinez stand over Rubio and say, “you better call 911 if you want them to save your life," according to the affidavit.
While Rubio was being transported to Methodist Central Hospital, he told Dallas Fire-Rescue, “my roommate shot me, and I think it was a 9-millimeter," the affidavit said. Rubio died at the hospital.
Martinez was arrested after police searched the residence and found a 9mm handgun, the affidavit said.
