HOUSTON --Detectives are trying to identify two suspects wanted in two robberies that happened just days apart in northeast Houston. The first incident occurred around 7:20am Saturday at a convenience store in the 1300 block of Hopper Road, according to a Crime Stoppers statement. A 41-year-old man was parked in the parking lot when a green truck pulled up near him. A man wearing a white T-shirt over his head got out of the truck and approached him with a long rifle in hand. The man demanded the victim's wallet and fled. On Tuesday morning, a 74-year-old woman parked at a convenience store in the 2600 block of Little York Road asked the occupants of a green truck to help her pump gasoline. Instead, one of the occupants approached her, reached into her vehicle and snatched her purse before fleeing. In both incidents, the truck has been described a green four-door Chevrolet truck with white magnetic signs on the doors that read "MC Foundation Repair." The first suspect is described as a Hispanic male between 20-30 years of age, stocky/obese with a long pony tail. The driver of the truck is described as a Hispanic male between 20-30 years of age, 5 foot 6 to 5 foot 9 with a short military-style haircut. Anyone with information regarding the suspects' identities is asked to contact Crime Stoppers at 713-222-8477.
