SAN ANTONIO — It’s been well over five years since Rhonda Hart has driven a school bus.  

“May 18, a yellow school bus. May 18,” Hart said. 

That’s the day when a student entered Santa Fe High School and opened fire, killing 10 students, including Hart’s daughter, Kimberly Vaughan. 

“I managed to drive my vehicle from the school back to the bus barn in one piece,” Hart said.  

Kimberly was a huge Harry Potter fan and was passionate about sign language. Kimberly’s school bus was parked behind Hart’s, who was a bus driver for Santa Fe ISD. 

“So she walked by me to get into the school and I said, ‘Bye. I love you,’ and I popped up our little ASL 'I love you' sign,” Hart said. 

That was the last time she ever saw Kimberly. The bus ride only brings back more memories, especially because Hart’s passengers know what she went through.

One of them was Manuel Oliver, father of Joaquin “GUAC” Oliver, one of the 17 students killed in a separate shooting in Parkland, Florida, over five years ago. The Parkland and Santa Fe shootings happened just months apart. 

Oliver sat next Hart on a bench facing 10 crosses. The crosses bear the Santa Fe victims' names.  with victims’ names. He cried as Hart spoke to him. 

“It won’t happen, it won’t happen to me,” Hart said. “Then it does.” 

Maunuel Oliver and his wife Patricia Oliver are touring 23 cities across by bus. Each one has been affected by a mass shooting. They're calling their tour “GUAC’s Magical Tour.” 

“This is the only country where you can go from one city to the other and find a memorial where innocent people were shot,” Manuel Oliver said. 

Hart drove the Olivers to Santa Fe High School, where she read a sign to them that explained how there’s armed faculty on campus. 

“This is total [expletive]. It’s more guns inside the school,” Manuel Oliver said. 

Hart served as their tour guide for the remaining Texas cities — Austin, Uvalde and El Paso. 

Hart and the Olivers went to the Texas State Capitol in Austin to call on lawmakers to take action on guns. 

They also reunited with the families affected by the Robb Elementary shooting that took the lives of 19 students and two teachers. The families hugged each other hard because of their connection through tragedy and pain. 

“I feel I can hang out with people who know exactly how it feels. I don’t expect anyone to pretend the feeling, they know it,” Manuel Oliver said. 

Hart drove GUAC’s bus, which has very limited AC, from Austin to Uvalde. 

“And so I am technically the shooting after Parkland and the first Texas school shooting,” Hart said.

Hart says if nothing changes, that list will grow.   

“I will support Uvalde and the next one, and the next one after that, so help me,” Hart said.
