District spokesman Jim Cummings said all students questioned in the inquiry have said everyone stood for the pledge and that none said their land had been stolen. "What we are finding here — and what we believe — is that the statements that he made weren't accurate," Cummings said.
A recorded message on Hill's phone said his number had been changed or disconnected. He didn't return two e-mails seeking comment on Wednesday afternoon.
The letter was distributed to other Republican senators by Pearce and was read last Thursday by another senator as lawmakers debated one of five bills on illegal immigration. Among the bills considered was one that would require the parents of students at K-12 schools to prove the citizenship of their children.
The district believes the instance that Hill referred to in his letter came during his March 8 stint teaching reading, writing and social studies at Harold W. Smith Elementary School in Glendale.
Substitutes are required to fill out a report after their teaching stint, and Hill made no reference in the form to the Pledge of Allegiance or land claims made in the letter. He did state that students "refused to act proper" but didn't provide specifics in that category or in the section about "inappropriate behavior."
The letter was the subject of heated exchanges on the Senate floor Wednesday as Pearce refused to apologize.
"It's read on the floor as factual," said Democratic Sen. Steve Gallardo of Phoenix, the Senate's most outspoken critic of the letter.
Pearce said no one from the Senate owes an apology for reading the letter. "It was all verified," Pearce said. "I'm disappointed that we assault and attack a teacher for speaking out."
He said the letter wasn't about Hispanics, but rather was about what went on in a classroom where students were disruptive.
In an interview after the debate, Republican Sen. Lori Klein, who read the letter aloud on the Senate floor last week, said she didn't regret bringing to light a teacher's experience, but that she doesn't believe all Hispanic students want to be gang members.
As to whether she believes the school district's findings thus far, Klein said, "I don't think the district wants to be embarrassed," Klein said.
The district had said earlier this week that it had no record of a Tony Hill or Anthony Hill working as a substitute. But Cummings said Wednesday that a closer inspection of records showed that Hill worked as a substitute teacher in the district for nine days this school year as an employee for a temporary service that provides teachers when the district's regular fill-ins aren't available.
Since Hill isn't a district employee, any discipline against Hill would be left up to the temporary service, Cummings said, noting though that he doubts any of the district's principals would be comfortable having him as a substitute at their schools.
A message left for Teachers On Call, the service that sent Hill to the district, wasn't immediately returned Wednesday afternoon.
