Officials believe the Houston-area volunteer firefighter threw the brick randomly.
Megan Cox, 21, was returning from an Astros game May 4 when suddenly her windshield shattered, detectives said
"She saw the suspect's vehicle kind of swerve into her lane," Harris County Sheriff's Sgt. James Dousay said. "The next thing she knew, she was struck in the eye with an object."
Cox has undergone numerous reconstructive surgeries since the incident.
"She almost lost her left eye," said Dousay, with the Sheriff's homicide division.
"It's sad," Kim Cox, Megan's mother, told the Houston Chronicle for its Friday editions. "This boy made a stupid choice, and now his entire family has to deal with it."
Kim Cox said her daughter's left cheekbone is now a metal plate.
"We'll pray for his family now. There have been a lot of rough times for all of us because of just one choice," Kim Cox said. "That one choice affected a lot of people."
Attempts by The Associated Press to find a home phone number for Kettler were unsuccessful on Friday.
