A 28-year-old is in custody in connection with a deadly hit-and-run. San Antonio police are crediting a tip with leading them to Joel Zaragoza. He's accused of running down Lisa Rosentein earlier this month on the service road of Loop 1604 near Northwest Military. An arrest affidavit says Zaragoza claimed to have hit a deer when questioned by officers. He is accused of failure to stop and render aid.
