Police have released a revised composite sketch of a man suspected of killing a teenage woman and wounding her girlfriend in a shooting at a South Texas park.
The June 23 shooting killed 19-year-old Mollie Olgin and critically injured 18-year-old Mary Kristene Chapa. The couple was shot in a park in Portland, about seven miles north of Corpus Christi.
Portland Police Chief Randy Wright said Saturday that Chapa worked with a forensic artist a day earlier to refine the sketch that had been released earlier this month.
Police say the suspect's description remains the same: a 5-foot-8-inch, 140-pound white male in his 20s with brown hair.
Investigators have not determined a motive for the shooting but have said there's no evidence suggesting the women's relationship was involved.
