Matthew Angel Tufono had just celebrated his 51st birthday with loved ones. Hours later on his way to work, he became trapped in the chaos of rushing floodwaters.

The flash floods that swept San Antonio early Thursday killed thirteen people, and all but one of the victims has been identified.

The Bexar County Medical Examiner’s Office has identified four more people who were killed in the Beitel Creek flooding on Thursday.

The abrupt closure comes after the city experienced record-breaking rainfall in the morning hours on Thursday. Between 3 and 8 inches of rain occurred in Bexar County, according to the National Weather Service. The heavy rains blanketed the region, causing power outages, high-water rescues and at least four fatalities.
