The two parents say over the last few weeks Katie had been receiving letters from the school over it all ... and in the past few days, she had gotten "kind of the final letter that there was going to be a trial or some kind of something."
Gina speculated it all might have led to the Stanford goalie's death on Tuesday.
"This is the only thing that we can come up with that triggered something," Gina said.
The school declined to comment on the situation ... telling "Today" in a statement, "We are not able to share information about confidential student disciplinary matters."
Devastated to hear the news today about Katie Meyer. All my prayers to her loved ones, @StanfordWSoccer and the entire @GoStanford family.
