The teenage suspect who allegedly shot two sisters, killing one of them outside Houston, before killing himself, apparently opened fire on the pair as they met with him to discuss inappropriate comments he previously made toward one of them, authorities said Wednesday. 

Walker J. Porretto, 19, was found Tuesday in nearby Montgomery County and shot and killed himself, Harris County Ed Gonzalez said. 

The shooting occurred at about 7:30 p.m. The two women shot were identified as Redha Sayed, 18, and 20-year-old Mahenoor Sayed.
