Emergency workers arrived on the scene 24 minutes after receiving a 911 call, but “due to the terrain and accessibility,” the crew had to walk to the location of the pond before they could begin attempts to rescue Chao, according to the incident report from a Blanco County first responder.

“The two deputies who were in the water standing on the submerged vehicle requested tools to break the window of the vehicle to perform a possible rescue. One EMS crew member donned water rescue PPE and entered the water with a Hallagan tool. One Firefighter entered the water wearing proper water PPE relaying tools to attempt rescue, several tools were used to attempt access to the victim,” the report said.
