Police say this case is an unusual one because it didn't happen near an overpass.
From now on, Tina and Kevin Morales will be avoiding I-35. They say the rock-throwing attacks have hit another level.
"It didn't come from an overpass. It wasn't just a drop and a lucky hit. I mean, that person targeted a single-moving vehicle that was by itself," says Kevin Morales, husband of rock-throwing victim.
They were leaving downtown Austin early Sunday morning and heading back home with another couple.
Ironically, they had just discussed taking the upper deck of I-35 because of all the recent rock-throwing incidents.
That didn't stop them from being targeted near Rundberg Lane.
"Out of nowhere! We were in the left-hand lane next to the median. Boom - it came through like a missile," says Kevin Morales.
A large piece of concrete flew straight through the windshield. It didn't stop there, Tina was also injured
"Shock. I literally thought I got shot. I kept on saying i think someone shot me in the neck, someone shot me in the neck," Tina Morales, rock-throwing victim.
Besides scratches and swelling, she says a bubble was found in her lung and now needs to see a pulmonary specialist. They're happy the situation wasn't worse
"We just need to talk about doing some fencing all along I35. How far down south and north to go? I mean, I dont know. We've got to start somewhere but something's got to change," says Kevin Morales.
APD says they're been around 41 rock-throwing incidents since June 2014. Five people have been hurt, two of them critically.
Most of them occur on the weekends around 30th to 40th St. In regards to this case, police say they are not sure if it is related to the others.
It happened much further north and was not by an overpass. The Morales' have some ideas as to what might've happened
"When he saw a single-vehicle by itself, he popped up and threw it. Or if he's in a vehicle, it would have to be two people, one person driving and one person throwing," says Kevin Morales.
They say making people aware of the situation isn't enough anymore. Something needs to be done because the problem is spreading.
"It's crazy. You just don't expect something like this, simply driving home," says Tina Morales.
