David Rocco Titus, 24, was shot once in the back of the neck and died in the early morning on July 25, 2015. He was found lying in the roadway in the 200 block of West 13th Street in San Angelo, Texas; the wound was fatal.

Investigators linked 47-year-old Stephano Miguel Culbreath of San Angelo to the killing. Detectives said Culbreath pursued Titus in a maroon Chevrolet Suburban, struck Titus’s bicycle, then shot him. Culbreath was arrested after initially being taken into custody on drug charges, and was later tried for first-degree murder. At trial the defense argued the investigation had flaws and presented no direct evidence tying Culbreath to the shooting; Culbreath denied knowing Titus. A Tom Green County jury convicted Culbreath and he received a 30-year prison sentence.

The trial record notes unanswered questions and inconsistencies about the investigation that left both families anguished. Does anyone have information about Titus’s movements that morning or saw a maroon Chevrolet Suburban in the area?
