Jose Guadalupe Martinez, a 50-year-old Hispanic man, was found murdered in his office at Milo’s Tire Shop, 2485 Military Highway in Brownsville, Texas, on March 15, 2017. Officers arrived after a call at about 7:49 p.m. and found Martinez face down in a pool of blood with a gunshot wound to the head; investigators recovered one bullet casing. A receipt shows Martinez made a dollar store purchase at 7 p.m., and the man who first discovered the body arrived at the shop at 7:35 p.m. — placing the time of the killing between 7 p.m. and 7:35 p.m.

The person who first found Martinez had returned with two other men; the three called police and waited. Family members said it had been an ordinary day and nothing seemed out of place. Justice of the Peace Linda Salazar ordered an autopsy; the primary cause of death was listed as a gunshot wound to the head. Brownsville police have reported having no leads and the case remains unsolved.

Who in the community might have seen activity around Milo’s Tire Shop between 7 p.m. and 7:35 p.m. on March 15, 2017, or who has information that could help resolve this case?
