The mother of two Lake Highlands students was killed Friday morning while crossing Central Expressway on foot. Police say they still aren’t sure why Trekessa Gordon-Matthews opted to run across the highway just north of Park Boulevard in Plano instead of crossing under the overpass a few hundred yards away.

The alleged hit-and-run driver, 31-year-old Carlos Alberto Cruz-Lobo, was found and arrested a short distance away. He had stopped his pickup truck to use a pay phone, though he did not opt to call police or medical help. The accident shut down the highway for almost two hours.
