On March 28, 2019, at 1:23 a.m., Williamson County Sheriff’s Deputy J.J. Johnson tried to pull Javier Ambler over for driving with his high beams facing oncoming traffic in a suburb north of Austin.

Ambler kept driving, and Johnson chased him across the county line and into the Austin city limits, which is Travis County.

Ambler tried to stand up, according to an internal report, and Johnson threatened to shock him again.

A body camera worn by Austin Police officer responding to the wreck showed the fourth and final time Ambler was tased.

“I have congestive heart failure,” Ambler told the deputies.
