The woman, whom authorities have not identified, admitted that she lost her temper with the opposing team, but said she threatened to "get" them, not kill them, and that the most dangerous thing she brandished was an angry finger.
Security footage of the incident, which took place in the parking lot of the Metzger Middle School in San Antonio, showed no conclusive signs of a gun, and police found no guns when they searched the woman's home and car.
At least six witnesses claimed that the woman pulled a gun when the volleyball team was celebrating a resounding victory over Metzger.
"Witnesses say she said she was going to kill them," school district spokesman James Keith told The Associated Press.
But the more authorities delved into the incident, the less certain those accusations seemed.
When police could find no evidence of the gun, they went back to the witnesses and the middle school girls to ask them again about what happened.
That's when they spotted "inconsistencies" in the witnesses' stories, Keith said.
No criminal charges have been filed against the woman, local TV station KENS5 reported.
Authorities did issue a criminal trespassing warrant against the woman, which means she's barred from entering any Judson Independent School District campus for one year.
In 2005, police said a Connecticut man attacked his daughter's high school softball coach with an aluminum bat. The coach had suspended his daughter for missing a game to attend a prom, The New York Times reported.
Also in 2005, a girls' high school rugby coach was attacked by a mob of parents in California after trying to break up a fight between a parent and a referee. The parents punched and kicked the coach unconscious.
"The emotional and financial investment parents have made in their child's athletics, coupled with the irrational intensification of youth sports, has sent a lot of parents completely over the edge," Bruce Svare, a psychologist at the University at Albany, told The New York Times.
