The officers pulled Schrupp and Morris over and told the 20-year-old that she owed money for a traffic violation and her license was suspended. They told her they had no choice but to arrest her.
"I said (to Schrupp), 'Stay calm. We are going to work it out.'" Morris told ABC News. "(Morgan) said, 'Anyone in the back of the car has to get cuffed.'"
The officers "released" her a short time later, and a moment after that, Morris was down on one knee.
"I wasn't focused on anything else going on around me," Schrupp told ABC News. "I was just focused on him going down on one knee."
She said yes.
"She thought it was a great prank," Morris told ABC News. "She took it really, really well and enjoyed it. I wouldn't have done it if it was something she wouldn't have taken well. We're still laughing three days later ... seeing her laugh is the ultimate goal."
