Carlos Armin Quesada-Martinez, a 41-year-old Hispanic man, was found dead on February 22, 2015, on a High Island, Texas, beach. A passerby discovered his body around 9 am; he was bound with duct tape and had been shot three times — twice in the back and once in the back of the neck. Family members had reported him missing to the Harris County Sheriff’s Office on February 17, 2015, after he failed to return home for several days, and detectives identified him with help from those relatives and other identifiers.

His 2006 black Chevrolet Impala was reported missing. Investigators have not determined whether Quesada-Martinez was killed on the beach or elsewhere and then moved to the shoreline. The Galveston County Sheriff’s Office says the investigation is ongoing and has not announced any arrests or named suspects.

Does anyone have information about Carlos, his last known movements, or the missing 2006 black Chevrolet Impala that could help investigators?
